I’ve played the original Raidy 2 on PC98 ages back (and i’ve fiddled w/ the jap re release to a lesser extent xD) and yes it is DEFINITELY much muuuuuuch better than the first its still a rather limited RPG if your used to the more recent gigantic world map scenarios these days buuuut if your comparing it to the first the gameplay is much more expanded. First off you finally do get to go to a town w/ Inn and weapon shop and all that jazz. The game’s dungeons are actually divided into 3 major areas/stages/dungeons which obviously have several floors containing several bosses.
Also it does introduce a money/item system so you CAN buy weapons and pots… on top of that the inv system has been updated so you also get other accessories that boost stats and are used to pass certain bosses in the game =3 Not to mention that obviously the H-scenes aren’t just confined to the dungeons w/ the town having its occasional moments or 2 as well depending how far into the game you are =D
Anyway i’m going nuts waiting fer no.2’s release @_@ (And praying that upcoming no.3 also gets licensed XD)
