Started playing Blue Box (Homes) Basic D& D in April, 1977. [2017 is my 40th year of D&D!]. Moved on to AD&D when it came out. I prefer the AD&D style. It has enough framework to give some boundaries, but does not try to be realistic about every little detail.
I have played fighters, magic users, clerics, and way back when a halfling fighter-thief.
I like a mix of role playing and roll playing. A little metagaming talk and off topic banter is OK, but like to keep on track.If you can't stop a minute to laugh at some situation, it's too serious.
I have played Metamorphosis Alpha, Gamma World, Boot Hill, Top Secret, Gang Busters, Star Frontiers, Villains & Vigilantes, Marvel Super Heroes, Traveller, and a couple home brews, but all way back in the 80's/90's.
I have so far played one session of a D&D Next game using G+ Hangouts and Roll20. (In my experience, that is the best way to do online roleplaying.)
I am looking to play some more before taking the plunge and running my own game.
