I started out with a Tetris console. I moved my way up to Nintendo where I have been playing tons of games from The Sims 2 to Pokemon (Silver, Gold, Platin, Soul Silver) and even Harvest Moon. The Dragon Quest franchise I encountered later on was a game changer. Truth be told, I didn't properly finish both games (Dragon Quest V , Dragon Quest IX) because of the sheer amount of play time. I literally deleted my save point after 50 hours of play time and never played the game again. Basically Nintendo games from the old times followed me throughout my whole childhood. When I was getting older and the demand for online games started to take place, I also played several MMORPG's. League of Legends, Tera, Neverwinter and a few more. I used to play all Assassin Creed games but lost track of it after Black Flag. I am also a huge fan of Skyrim and GTA. Far Cry, Sniper: Ghost Warrior or Metal Gear Solid - I will probably play any game as long it doesn't take years to finish. Some people complain about less playtime while others complain about a tremendous amount of.
I belong to the latter one Anyways I digress. Mainly RPG but I wouldn't mind for a round Cs:go or any other game.
