Heres my summary.
PC - Best to play most games.
OpenTTD | Open source wonders. Get involved, join in, contribute, and try to solve that overcrowding problem on the mainline.
Rollercoaster Tycoon 1-3 | Chris Sawyer strikes again!
OpenBVE - Great realism, crappy graphics usually.
Watchdogs 2 - Great to mess around with people.
Watchdogs - Good concept, scummy protagonist.
GTA - Illegal fun. (MI5 is looking at me through my camera lens as I type this.
DTG Train Sim - Rubbish, please steer clear of their crap.
Faster Than Light - Much fun, but so frustrating.
Minecraft - Creativity through blocks.
ETS2 - Calming when there's no traffic.
Surgeon simulator - Sorry I killed you Bob, needed that 10 second death achievement.
Nintendo games - Immense childish satisfaction, wish I still had my DSi.
Terraria - Can't continue it because of the spiders.
GMod - For the occasional doesn't make sense type shenanigans.
Lego games - More childish fun.
Trainz - Don't buy it.
Prison architect - Immense hours of enjoyment.
Infinite flight - If I can't figure out how to play this properly, how am I supposed to move on to FSX?
OMSI - Glitchy crashy realism.
Mini Metro - Just play it.
