[Advice] Great games for 3/3.5 keys?

Take my Skyrim for 2,5 keys! :-)

Wait for a sale and buy discounted games from your wishlist.

The Forest

Team Fortress keys? <- I'm new to this?

How did you get them? P.S. i dont know what games you like so i cant realy suggest you something.

Killer Is Dead is up for 2.5k.
Stronghold Complete Pack for 2k.

I'd wait till the Halloween sale, though.

Wait for the next sales... for example: you can get Dead Island collection (2K) + Mortal Kombat Komplete edition (1K+1TOD) for those keys, and if you have some luck you will get 1 or 2 refs too hehe

Saints row ultimate Franchise Pack

I got the 2 Transformers game for 3.5 Keys yesterday.. I think I could even have pushed down to 3 Keys.

Most 20 euro/usd games which get a 75% off sale can be bought with 2 keys.

Wait till halloween sale.

CS GO ....
