I just started it the other day, and I'd say it's on par with BB/VW shockingly enough.
Also I first did the "classic version" but quickly decide to do the "complete version" as weaker pokemon were usable in it. That and it's not a overboard rom hack that gives Youngster Joey 6 Pokemon at level 10...
Giving the first Gym leader 6 Pokes a bit rough, but their at tolerable levels so it's cool.
I got a Eevee,Shinx, and just got a Poliwag (Use Old rod in Violet City) on my team btw.
