Blacklight retribution was a decent FPS that once had a presence on Steam, but it seems they moved to their own platform.
Honestly, Warframe is a tough game to start with, but it becomes enjoyable when you play with someone else. If you enjoy it, taking advantage of the 50%-75% discount from Login Rewards will let you reach the highest Platinum tier (4300 for $199.99, which is between $50 and $100). With Platinum you gain access to more weapon slots and Warframes, making the main constraint being having enough free slots. You can remove items to create space, but I prefer keeping everything since I've invested time in it. For any Warframe questions, feel free to ask me or check the game's wiki at http://warframe.wikia.com/wiki/WARFRAME_Wiki
It's similar to Heroes of the Storm, but you have to pay to retain the hero. Gaining in-game money is slow. The rotation might be frustrating because in Dota you can use any hero whenever you want, and it's clear as a day.
