So, from my understanding, Steam does its job so well when it comes to platform services and prices, that people end up buying more games that they need to. In any case, that doesnt really sounds like a problem. I'd rather have more games available, than none at all. I mostly care about having a variety; I dont see my backlog as something that needs to be completed 100%.
Anyways, I bought Age of Empires but I ended up refunding it because I find its gameplay tedious (Im a BW and C&C guy) so I have 11 euros to spend in my steam wallet. Give me some good recommendations. Action games,fps,rts, are my taste
