Ranked in these QuestionsQuestion Ranking
Pros
Pro No VR sickness
Since the player and the character are stationary with the vehicle creating a frame of reference, much of the issues with motion sickness are avoided.
Pro Accessible to non sim players
While Project Cars is a hardcore racing sim, it still stays accessible for unfamiliar players through easy to understand design.
Pro Simple VR setup
The game auto-detects Oculus Rift, making setup a breeze.
Pro Finely tuned AI
Users can set what kind of AI they will be racing against each race, allowing you to make the game easier or harder if you wish.
Pro Endless solutions
With proper planning, users can "code" together very precise ways to create all the things needed for the game, some in very inventive ways that can differ quite a bit. This allows for tons of replayability.
Pro Under active development
The game is still in Alpha which means endless future possibilities.
Pro Massive and infinite procedurally generated world
The playing world is as large as you want to explore, it automatically generates it as you explore more areas.
Pro Cooperative or PvP building
Factorio also supports multiplayer, allowing many players to cooperate and assist each other, or work against each other in PvP. By default, multiplayer games run the CO-OP freeplay scenario where all players work together to launch a rocket with a satellite into space.
Pro Charming old school graphics
While not the most technically advanced graphics the look of the game is much like a game from the 90s but seeing it in action when an assembly line starts moving there is an impressiveness to it that suits the game quite well.
Cons
Con Horrible optimization for AMD
For those that use and AMD CPU or GPU the performance is way below optimal with AMD performance at about half of what Nvidia and Intel chips are seeing.
Con Menus don't work on Occulus
Users are unable to control the menu in Occulus as the menus do not show, some workarounds are to close one eye to see if you can see a menu or use a tool to broadcast the Occulus image to ones monitor. Either way this can be a frustrating experience and needs to be worked out.
Con Buggy gameplay
Even though the game is fully released and out of early access it is still filled with bugs and balancing issues. From strange physics to graphics that flicker, the game has the appearance of a rushed product that was not ready for release.
Con AI can vary wildly
Even though the player can preset the AI before a race, the AI can still behave in strange manners, some drivers being really aggressive while others too passive. It is a strange mix that can make for some uneven racing.
Con Can become rather repetitive
There's really little payoff for being able to build really long chains of automation, it usually results in being able to open a new tech tree which allows the player to continue the process of building automation chains ad infinitum, which, admittedly can become rather boring after a while.
Con Still in Early Access
The game is still in Early Access which means there will be bugs as well as missing features.
