1. Fallout the MMORPG
I've always been a die-hard fan of the series, and considering it's leveling system is, in my opinion, damn near flawless, I don't think that basic character conception would be overly difficult. Plus, the setting and the backstory are wonderful. Some of the most dedicated fans on the planet too! I'd quit my dayjob for a Fallout MMO
Cyber-punk/Street mercing and Mr. Johnson's. Though a lot of people might not be familiar with the series, it's been around for a long time, and with some work, it could turn into a wonderful MMO experience.
Not really an MMORPG, but it could be with some work. The idea of organized factional warfare hasn't really been taken to extreme levels thus far, save for DAoC and Anarchy Online. Crafting advancing with technological upgrades in an organization could also work in a manner similar to Eve.
If you agree/disagree, feel free to let me know.
Post your own dream MMO's to be produced, with a slight summary of why you feel it would do well.
Waiting for something fresh to arrive on the MMO scene...
