When comparing Battlestar Galactica vs Arimaa, the Slant community recommends Arimaa for most people. In the question“What are the best board games?” Arimaa is ranked 30th while Battlestar Galactica is ranked 38th. The most important reason people chose Arimaa is:
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.

Pros

Pro Hilarious party interactions due to hidden cylon players
The game is at its core cooperative. However, the fact that there is at least one Cylon in every game, the distrust between players provides interesting party dynamics.

Pro Well reflects the series' atmosphere
If you are in atmosphere while playing a board game - this is the one to go with. The heavy use of the Battlestar franchise gives a sense of depth that is missing from other similar types of games. With the extra expansion available there is even more depth and atmosphere added to the game as well.
Pro Easy to learn

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 Needs a few playhthroughs to learn all the rules
With 3 expansions, which add their own rules and mechanics, fully understanding all the game rules can take some time.
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.
