It's a real shame Steam doesn't let us browse by tag, developer or publisher, offer recommendations based on what we and our friends play, or allow us to maintain wishlists. Forcing us to only choose between the 20 most recently released titles has truly hampered us all.
I've got a handful of indie games and they aren't that bad. Just gotta look for the quality titles. A lot of the games on Steam are just filler that I have no intention of ever buying.
I never purchase early access games, especially if the are from an indie studio. I feel like I risk losing my money if the game isn't that great. Steam should have a refund option for early access games. I'd probably make an investment then if I could get a refund if I opt not to continue to support the title.
