A good game?

Free game, i suggest:
-Planetside 2
Awesome games, i suggest (not free):
-PAYDAY 2
-Rocket League

You should try Overwatch, i'm having a lot of fun playing it^^

CS:GO, Dota 2, Nosgoth, Hearthstone (Battle.net) - they have many things you can buy =D

BF4 for $4.99 :) (Origin though)

Warframe is probably the best free game in my opinion.

Heaven Strike Rivals free to play fun little game heavy pay to win in pvp because you buy units at random with cores witchcost real money. I can't spend cash on cores but I still like it collecting the units is cool if you play lemme know so you can use my captain code get 5 free cores lol.

Brawlhalla (free 2 play)

What kind of genres do you like?

Pretty sure that a few days ago you created a thread about how you've got a new job and you're selling your steam account for 35euro. Hmm, anyway, you want to play with someone? You want to play by yourself? What genre do you prefer? I would suggest Path of Exile (free), Guns of Icarus (not free; you can buy a lot of things from their shop with Steam wallet and it's quite fun if you have 1-3 people to play with), Unturned (free, minecraft-ish with inventory items that can be traded on market).

Check out a game called clustertruck. The game is currently in alpha/beta or something and everyone can download and play about 15 levels. The game will be released on steam later this year.
