So I'm looking for a computer game that I can play for 5 minutes and enjoy, or 2 hours and enjoy. A game that has awesome gameplay and a lot of customization (I don't care in what sense, i.e. character customization, car customization.. I just want possibilities). I'm thinking something not to hard on cpu specs, I have 2 gigs of ram and a dual core processor, my graphics card isn't the best but it can handle diablo 3 pretty well... hope that tells ya something. I'm looking for something single player mostly, but with multi-player ability.
Not knowing your preferred gametype, its kinda hard to suggest something.
But here goes.
If you are intoFPS, id say borderlands and borderlands 2 are awesome. lots of wierd gameplay, random loot, somewhat challenging. Great multiplayer.
For something more similar to D3, there is torchlight, D2, or heck even that Path of Exile to try out.
The game i always tend to go back to when bored is Aquaria by Bit Blot. that game is so awesome. But its not for everyone i guess.
Aquaria has a no multiplayer tho, but its a huge underwater world to explore and unlock new abilities to overcome the obstacles ahead. in a somewhat open world type thing.
