Personally for me the best commercially released indie up to this date is definitely
Rush Rush Rally Racing. The guys at Senile Team did a stellar job making this game, it's a highly addictive unforgivable racing game with lots of extra unlockables and even has 'achievements'.

This game could have easily been released as a official licensed product back in the day and compared to other racings games on the system, this game is unique in both gameplay and presentation.

I'm very excited to see Alice Dreams Tournament completed, but I'm especially anticipated for Age of the Beast.. the DNF of the Dreamcast
It's done, when it's done. Hopefully this one will finally see the light in 2016. Also my interest is peaked for Xenocider, seeing that will be the first fully 3D indie effort on Dreamcast. And well actually every other project in the works is something I look forward too, lol.
