I believe that Lufia 2 goes for about 8 weeks from March 16 (as discussed briefly in the Voting thread for the 3/16-31 time frame). Which means its run will end on May 11th, unless you want it to run until May 15th to match the time frame for normal game runs.

As for my nomination I voted for Final Fantasy Legend 3, but since we are still going on with Lufia 2 (unless it is decided to end its run early), I think I will change my vote to The Twisted Tales of Spike McFang (SNES)
