>>37192832Honestly, I think FR/LG are easy enough games that you'll probably have more fun going in underleveled. I'd go for it unless you really don't want to, Vs. Seeker leveling goes by fast.
Pokemon is a repetitive game. You could try hacks/fangames, ROMhacks usually only change the teams you're fighting and the things you're encountering so if you want something more difficult/new encounters that's the way to go. Fangames are more interesting but it's still the same game at the end of the day. I'd give them a chance (I don't know many fangames but I heard good things about Uranium).
>>37192899Shroomish evolves soon and hits it with Mach Punch. You could also go for Rock Smash Loudred which is a lot weaker.
