i realize i should be working on gen 1, but honestly, all of the ones that are left are being worked on now like ledia has noted. and then the ones that are not made, i hate with a burning passion (i.e. the machop line and magmar) besides, when this gen is finally complete, i would think the starters should be next priority and since snivy is my favorite starter, i want to work on that line.
in short, i'd much rather continue working on pokemon i like, rather than ones i hate.
