What other cool games do you play??

[run SPOT run]

I play Cash of Clans, Clash Royale mostly for the social aspect...while traveling the country I've met (irl) half of my long time clanmates...I don't really care for the gameplay anymore, it gets a lil boring once you've lvled up pretty far.
Some of the other .io games out there are fun, I really only will play splix.io and slither.io, and dont think most .io games are as well ballanced as agar.io...
As far as mobile games I love playing "heads up" when I'm with a rowdy crowd, but it isn't a solo type game. Still occasionally fire up the good ol temple run or subway surfer. I don't play Boom Beach anymore, but it's not a bad game (like COC but ww2 era and different strategies). And of course there's always trivia crack which can be fun especially if you have friends to challenge.
If your really looking to get into p.c. gaming, look into http://store.steampowered.com/ there's a ton of free games and subscription games too for a reasonable price, and most of them will run on an aging machine.
Good luck, and happy gaming!
