I agree with Nightcrow, if you don't know squat about something, do something else. A great example of course is the old bootlegged pokemon Diamond. (BTW hup holland hup)
Stuff I don't like...Didn't I already post in this thread once? Can't remember. Grammar errors, lots of typos et al. To be honest, when I first started playing Brown, I quit because of the errors, and I only played it again because someone said I really should. Deep inside, I still hope Coolboyman will remove his errors...
Missingno.'s. It hurts me to say this, but, looking at you again, Brown... Missingno. is a mistake in the games or something, and not a pokemon, or something like the ghosts. Sorry everyone, but I had to say it.
Fakemon. These days, even Nintendo finds it hard making new pokemon, and some suck, so if they can't, you can't either. Theirs are canon at least.
Bad tiles. It's the whole overworld we're talking about, so make it look nice.
No updates. It's not like I want a beta, but at least some screenies from time to time, or simply a post that the project isn't dead.
The hero talking. HE IS NOT SUPPOSED TO TALK
It's all I can think of now. Keep in ind that this is my personal opinion.
