So on the one hand... SM was indeed somewhat janky, and didn't seem to offer anything new and exciting compared to any other FPS in about the last five years. The gravity forgetting to reset itself between rounds was especially egregious - Unreal Tournament had a zone/volume system for localised gravity in 1999, for goodness' sake.
But... It existed. It also mostly, in its quite basic form, worked. It's something that, given some time and a lot of love, I could maybe see myself wanting to play someday. Honestly at this point that shouldn't be high praise, but it's more than I expected, so fair play to CIG.
