my best game was the crew until they made the terrible update wild run.
but so far i have a lot of good games. blade kitten was also really awesome.
in case of free 2 play it would be Eternal Senia because it was so sad @ end :( (and takes out a lot of RPG Maker games that you purchased...)

you can also go there: http://steamcommunity.com/groups/Himitsudayo#curation there are all the games of steam i recommend.

thank you so much, 5566

Does it have to be released in 2015? I don't think I played a game released this year? The game I played most is probably Dwarf Fortress, once I open that some kind of black hole opens next to me sucking in all my time.

Thank you ;D

I dont care anymore about what game is best. Thanks!
