Pros:

Scootaloo.
Fourth poster *is* Babs.
Almost... excessively thorough. (Y'know that graffiti that you only read when your teammates are taking forever to load/keep going off to do things... read it)
Reminded me that the CMC theme song is badass.
Seriously, it's astoundingly thorough.

Cons:

Not the mod's fault, but I like the Midnight Riders too much to use this for any purposes but annoying my non-brony friend when we have LAN parties.
The songs get cut off weirdly when tanks show up. I suppose there was no real way to avoid this, but it's just weird.

Conclusion:

I thought this was a horribly dumb idea until I tried it (and, honestly, I only tried it because I thought it was a dumb idea), but it actually is extremely well done and *extremely* thorough with its replacement of all things Midnight Riders. The weird song cutoffs detract from it a lot, though.
