I am doing a Poison-type run. The whole FireRed portion is actually in the latest page of the Monotype thread, in case you want to check it out!
But yeah, it's not ALL writer's block, but I did have difficulty deciding on how to move the plot along, which didn't help, so I'm solely blaming that! :P
I remember I did a Normal-type run once, it wasn't too difficult, but that was on Red, where Tauros just kills stuff, so that definitely helped!
