Would you believe there is still someone developing new games for the Sega Genesis/MegaDrive? I recently learned about a game called Beggar Prince. It claims to be the first commercial Genesis game released in the US in nearly ten years. Check it out here:

It looks like it might be a fun little RPG. It's 32 megabits, which makes it even larger than Phantasy Star IV. They're taking orders for the third printing now. I'm thinking about ordering a copy myself. It would be cool to have a new Genesis game again after all this time.
