Game suggestions?

Hello everyone i was wondering if anyone can help me in what i could buy on steam. Now i have 15 USD on wallet maybe if the game really worth it i can put a little more money but not that much. I love online games where you level up your character and maybe get some gear (maybe have different classes) or something like that maybe like a mmo's, also love retro style games, i've been playing a game called "Hero Siege" its really good but i kinda got bored and wanted something new.

I dont mind if the game is retro or like a mmo this was just a example of what i normally like, just recommend me what ever you like and ill search it. Thanks <3

If you like older style games, I lately found an awesome, crazy arcade type game that I love to play! I haven't beaten it yet, it's only $4 but totally worth every cent!

PS. When you beat it, post here so we can talk about it. I think there is something hidden behind it, a story maybe? Not sure..

Borderlands is a really good game, and his secuel is better. you'll have a really good time with those
