Pros
Pro Lots of expansion boards available
Currently there are 8 licensed expansions on the manufacturer's site. There are also many fan made expansions available online as well thanks to the games large and friendly community. Both the manufacturer's and community expansions add plenty of new content to the game including cards, investigators, board addons, Heralds (mini-bosses), Ancient Ones, spells, and items.
Pro Scales well from solo to large groups
The game supports up to 8 players, which is something of a feat for a game of its size and components. Makes for a great party game due to the size of players it allows. However, at the lower end it can also be enjoyed with one or two players, making it great for intimate gaming session. No matter how few players you have available, you'll be able to enjoy the game.
Pro Great challenge for those that enjoy difficult games
The win conditions of the game are quite slim and require one to know the rules ins and outs, so while not a game for casual players it is a game for the hardcore who enjoy a challenge.
Pro Well-crafted
Big map, lots of items and heroes with their own graphics, player figures on plastic stands; lots of tokens and monster cards made of firm cardboard.
Pro Lots of choices
Each location offers you different opportunities to trade for and to explore. The imaginary hero class (like tank, mage, support, stealth) is up to you and usually not well-tied to hero abilities.
Even when apocalypse comes, you still (might) have a chance to defeat the planetary evil.
Pro Great atmosphere of Lovecraft tales
Your weak heroes have to dive into parallel realities, use magic, defeat unknown guests and apply unique artifacts. Each game's location has its own secrets and 'contacts' with various outcomes — good and bad.
Pro Role-oriented
You either choose by yourself or get a random hero, and play with them the whole party (if you were not killed, of course). You and your hero have skills, items, unique qualities and effects, and their story.
The game itself encourages role-playing elements to dive into the Lovecraftian environment.
Pro Highly cooperative
Though the rules do highlight "best players of the game" via basic calculations, the game itself is aimed towards collaboration. To win, everyone must commit to the victory, and you often forget about the existence of a "best player".
The game allows players to exchange items or help other players via skills, special abilities and magic. In practice, players often compete their tasks in pairs and more, e.g. they close gates in pairs, where one has to clean the entrance from monsters, and the other seals the gates.
Pro Each game is unique
The game starts by choosing a random boss and/or heroes. Each turn begins with the myth phase, whose effects apply from a random card in the deck. These effects include monster movement, game-wide buffs and de-buffs, quests, monster gate breaches, etc. You will never know if you will be able to win the game.
Items and skills are usually taken randomly too.
Pro Easy to learn
Arimaa is a game suitable for both young and old, it was made to be intuitively simple but with a lot of depth. Even the setup follows this premise - you set up the figures in two rows like in chess, but you can place them in any way you like.
The rules are simple – in your turn you have four actions. You can either move a figure four times, move four figures one time, or do any combination in between. All figures can move forwards, backwards, and sideways apart from rabbits who can’t go backwards.
You can use two actions on a stronger piece to push or pull your opponents’ weaker figures. These stronger figures also “freeze” adjacent weaker pieces, preventing them from moving unless there’s a friendly piece next to them. If a figure happens to walk into one of the four trap squares or get pushed/pulled into one without a friendly piece next to it, then it is removed from the game. The first player to get a rabbit to reach the opposing side wins. The game can also be won by removing or immobilizing all your opponent’s rabbits.
Pro Active online community
The official site of Arimaa is quite lively and features reviews, downloads, the latest news, an active public forum, and much more. There’s even an online gameroom, so you can play Arimaa against computers or other people in either turn-based or real-time games. There are many people online, so it shouldn’t be a problem to find a game.
Pro Can be played with a chess set
In case you don't want to purchase the gameboard made by Z-Man Games, you can use the components of a regular chess set. It also helps if you have four coins to mark the trap squares. You probably already have the equipment you need.
Pro Fluid gameplay
The 4 moves per turn gives Arimaa's tree of possible moves a very high branching factor. (It was invented for AI programmers as a game more difficult to program for than chess, but easier than Go). You can't think several turns ahead like chess (the space of possibilities is too big), instead you have to think in terms of distances and capabilities, giving Arimaa a very fluid feel.
Cons
Con Very unaproachable
Arkham Horror has a lot of moving parts, its rules are difficult to follow, and the gameplay itself is pretty difficult. This all adds up to a game that is very unapproachable and will take the most dedicated of players to really understand the whole concept put forth.
Con Huge rules
24+ pages of rules. Though they are well-written, highly illustrated, enriched with small data tables, it is easy to forget small details, especially when some critical rule is applied, e.g., for just one type of bosses.
Con Long
The game is very long (several hours).
Con Playing alone or in small team (2-3) is usually easy and boring
Arkham is best enjoyed when played by teams of 4 and more.
Con Long preparation time
Laying out all the things may eat up to 30 minutes (without extensions).
Con Hard to find
It was actually released in 2005 and currently out of stock at official page.
Con Requires constant engagement
Arimaa can get out of hand quickly because there’s pretty much no way of predicting how future turns will play out. This is because it’s significantly harder to pinpoint four actions that your opponent might do as opposed to one action in similar games to Arimaa. Due to this the game requires the players to continually pay close attention to what they’re doing, which isn’t inherently bad, but can be a bit problematic for people with shorter attention spans or for people who don't want to take the game too seriously and just play it for fun and socialize meanwhile.
Con Quite long to play
A game of Arimaa is very unpredictable and can often lead to a very long session. The time can vary between 15 minutes and 2 hours, so it’s not great if you’re looking for something that you can quickly grab and play through.
