Pokemon belongs in Blockland as much as TF2 and Halo. It's a sandbox game, download what you want.
Anyway, ouch man. Hopefully you can loop it at a point closer to the beginning.
Anything can belong in Blockland really. It's up to the author to make it the right quality.
But the difference between said content being in Blockland is that Pokemon has more ways of going about it, while TF2 and Halo don't give too much of a concept when it comes to implimenting them into Blockland.
