Joke. What...? Too soon? Nah but seriously, it'd be cool if people started to do RTA of Marble Blast Gold, since you have to play and think the game completely differently, and it increases the replayability value. At the moment, I'm working on getting a time for each category: beginner, intermediate, advanced & Any% (all 100 levels). If you're interested to try it yourself, make sure to read the rules first, but most of all, have fun!
Btw, feel free to post your times in this thread... for bragging rights. Go hit that Rigel with some competition!
