It's not an RPG, but this is one of the most memorable indie games I've played in the last couple of years. It's called EmberWind and it's a Ghouls 'n Ghosts type game. http://timetrap.se/emberwind/ . And although this is an oldie, it's certainly a goodie: Mr. Robot by Moonpod. I played, and enjoyed, it years ago. http://www.moonpod.com/
EDIT: And, yes, indie gaming is becoming more well-known and wider spread. It's like we, as gamers, struck oil and the underground is flooding. It's difficult to keep up with stuff, be it RPGM stuff, the RenPy stuff, Spiderweb Software's stuff, all the stuff out there.
I can already tell you that I missed a lot this year. Just last night I tried out the demos for Planet Stronghold http://www.planetstronghold.com
and Alpha Kimori http://www.alphakimori.com
. I liked them both. (I also tried out the demo for this otome called X-Note http://zeiva.net
. It wasn't bad, but it wasn't superultrasexyawesomewtfbbq either.)
It's like with music. It's hard keeping up with all the local bands out there... and in the short time my band's been kicking, we played with some fantastic acts I'd never have known about otherwise. And there's always local shows happening, which is great since I like to see what's out there musically. Because, let's face it, most stuff on major labels and the radio is corporate swill.
