I'd happily pay for more SC2 non-competitive in-game items like skins, announcers, etc, if only they'd make more. Even the ones that exist, I missed the window/requirements so can't even pay for them.
StarCraft/Brood War was the most fun I had playing 1v1 and FFA. It's hard to go back to the janky unit routing, small control groups, etc after being spoiled with SC2. The Remastered graphics update is nice but somehow loses some of the charm. It's more pleasant to watch now than the VGA graphics would be though. Was there ever a Brood War units/maps done in the SC2 engine?
I genuinely hope not. Not everything needs to grow and StarCraft 1 is fine the way it is.
