I'll focus on FPS games.. Got Plants VS Zombies: Garden Warfare on Humblebundle a while back, been playing it a lot since ban. It's quite a lot of fun and extremely casual. PM me if you want to play together over TS or something someday.
They got so many games out, some free to play and others you have lifetime after you buy the core game the choice for me is hard. Wildstar Elder Scrolls online Star Wars online Star Trek online Random Korean shooter with a chicks tits and ass hanging out (then the game closes a few months later another soon starts.) Diablo III StarCraft II Guild Wars II Planetside II And many.. many more if you have a steam account and look at the free to play section alone.
You would like to youtube it. I like the AH since it was like GW2 as far as placing buy and sell orders. The private house is something like the wow garrison just not near as big and no NPC's or pets walking around (that I know of).
I just downloaded the free version of swtor tonight and popped on 5 or 6 levels. Game seems to be ok so far. Dont know about end game but so far it feels similar to wow but its sort of nice seeing different maps and style after 10 years of wow.
