Space Gadget Normal Time records are redundant. The best times would all be ties, much like Bridge Zone 2, but harder due to the subseconds, but do we need another Bridge Zone 2...? Space Gadget Normal Score records are good though. I'm all for Chaotix * Score missions, they are quite different except for the TA missions (Grand Metropolis, Rail Canyon and I think Egg Fleet where it's the same mission as the normal mission, but you're given a time limit ala Mission 4s/Sonic *). Sometimes you are given more objects to find (double the items apporximately, like Bullet Station and Seaside Hill) or you are given completely new objectives, like Mystic Mansion. I think it's valid competition. Also, I'd also like to bring up possible Boss Scores. I know there would potentially be a max I think, nor is a time bonus given and nor is score tracked, but I find it kinda interesting, maybe it's a bad idea... :/
Also magnum, TBG going to Freestyle has a slim chance of happening now. Metal Madness is a done deal and most of Rayku's Team Dark boss times, but others are more difficult to spot and with Rolk pwning SC and STT, there is even more of a slim chance of it getting done... :/
