I'm 35, I too suffer from motion sickness but only from FPS... its a good job I don't like playing them except for the odd title like borderlands /2 and dishonor.
I used to be such a hardcore gamer in the days of Sega Master System, Megadrive and Super Nintendo, but since I've gone to uni, that's when it kinda trail off. I still brought the playstation, playstation 2, playstation 3 and Nintendo GBA and DS, no doubt I will get a PS4, vita and 2/3DS at some point too. But the games I tend to play have been limited normally Street Fighter and the odd platform and driving game.
Its only recently since I've been living on my own and not much cash that I've been pouring the hours into games and started to enjoy it. I have a massive backlog of 'retro' games to catch up on.
