I hope your don't mind, Bloodphantom, but I edited your post to put a white wolf icon on it, to make it easier to track. I highly recommend that, in fact, to anyone with a non-d20 thread, based on a discussion in meta.

As for Psion's point, I agree - you can't MAKE someone do anything. However, if someone's interested in pitching a new system to the group, the burden falls on them to make it fun. Any time I want to have our gaming group try a new game, I put in the same kind of effort as a one-shot at a gameday.
1. I make up pre-generated characters, with interesting abilities that showcase the system. I give them a one or two sentence description, the kind that a movie character would get in a promo.
2. I come up with maps and props for the adventure that attract the players' interest.
3. I come up with a simple goal-oriented adventure that can be finished in a single 4 to 6 hour session.
It's a lot of work, but what you've done is remove the veneer of "learn a new system, learn character creation, learn the goals of the game" - and stripped it down to its bare essentials of roleplaying: Role-assumption and having fun with friends. Past that, it's up to your skills as a DM and the system's strengths to make new converts to the system. And I have often found that, if people first experience with a new game is memorable, they will go out of their way to learn more about it, pick up the materials, slog through rules of moderate complexity, etc. - just based on that first impression.
But it's up to you to give them that first taste of a fun new system.
