As a Megaman fan, I feel that the series is over-represented on the star list, though I wouldn't know which ones to remove.
With SMW, I'd suggest unstarring
this run. I would suggest this
Kid Chameleon run as a potential replacement, but the rating suggests otherwise. :/
I would like to suggest
Sub Terrania as a star-worthy candidate. To my knowledge, it is the only game of the Asteroids/Thrust-genre on this site, and it's significantly faster-paced and more varied than other games of its genre would end up being (such as Solar Jetman). The death-abuse helps give the viewer an idea of the craft's fragility, which makes the health-management and super-fast speeding around much more impressive. Watching the run is what honestly got me interested in playing the game for the first time and falling in love with it.
