TL;DR: mariokart is messing with map compile. Is it OK if I take it out?

So guys, in the past 3 days I've been trying to compile the map with a few of the suggestions you have made. However, after !!5 hours!! of the compiler running, it crashes (during the VVIS portion of the compile).
This means that the map has got too big. My first instinct would be to remove mariokart, since it's chewing over 60% of the total resources that the source engine allows for the map data. However, I'd like to know your opinions on the matter of the removal. Keep in mind that i can add other stuff in its place.

Cheers.
