It really depends on the game for me. played some really fun games or some super time consumer gaming sessions that i totally forgot to eat or drink for pretty much the whole day.
I have to say role-playing games are just super fun. I really use to enjoy mmo games but realize i got tired of developers changing stuff in the games too much where they just were not fun anymore sadly.
My first time was 17 which isn't too bad i got to say, just weed but tried molly a couple of years later and that was too much for me, fun but to much.
