Talking about Dread, Greg K said:
I like the version with dice
Version with dice? As a huge fan of Dread and Dread variants, I'm deeply intrigued. I wasn't aware of any workable dice variants.
Also, on the topic of Indie RPGs to recommend: Dogs in the Vineyard is a very interesting Indie RPG. Doesn't work for everyone (which is true for just about every Indie RPG--they're less "one size fits all" than conventional RPGs), but it has some great aspects and some players (including me) love its system. In particular, I like the way it can handle social conflicts, and the degree of choice it gives players--are you willing to get shot to prevail in a conflict? No? Okay, you can walk away unhurt, but you lose the conflict. Yes? Okay, then we see what happens. And are you willing to shoot back, or do you stick to just talking? I like the default setting (religious enforcers in the Mormon settlement of Utah in the late 1800s, with the serial numbers filed off), but if it doesn't work for you, use a different setting--Star Trek works particularly well, as long as you go with meaty moral conflicts that the characters really care about and that the players can really grok.
I'm in the thumbs-down on Prime Time Adventures camp, but again, just because it doesn't work for me doesn't mean it won't work for you. I don't like the indirection of playing a game that's about a TV show. I don't want to be playing a game about a TV show about something cool--I want to be playing a game about something cool.
Time & Temps is also a fun Indie RPG--if you like wacky time travel in the mood of not so serious Doctor Who, it's tons of fun. That said, while its system has some cool elements, it's wonkier than many--I find it somewhat unintuitive and complicated, even though it's pretty light-weight.
For a set of Indie RPGs to try out, I'd go with Fiasco, Dread, and Dogs in the Vineyard. They each do different things, and they're all awesome for the people for whom they work well.
