What are some games that too few people have played?

I know of a lot of indie games that are actually really good, and I'm hoping to find some others. Here's my list:

• BPM: Bullets Per Minute
• Hedon
• Ion Maiden
• Prodeus
• Project Warlock
• Tower 57
• Wrath: Aeon Of Ruin If this list is incomplete, help by expanding it :)
