Instead of bragging about it in a desperate plea for attention, you could just save it until you find something that personally interests you.
I find that if you have to rely on other people to tell you what to buy, it's a sure sign that you're not ready for what reality has to throw at you.
How is he bragging and begging for attention? The OP literally is just asking for recommendations of steam games to buy. Stop it with this passive-aggressive crap.
OP, I'd highly recommend the following for $20:
(I'll admit, these are some of my favorite games, but I've provided gameplay trailers so you can see what they're like for yourself)
I'd add more but I have IRL stuff to do, so feel free to check those games out. I highly recommend getting Half Life 1 and 2 though, they've got the longest combined gameplay stories for the cost. Left 4 Dead 2 also has very high replay value for its multiplayer gamemodes. I'd even play it with you if you'd like, it's fun
for the whole undead family.
