Is there really more detail to the worlds in Re:COM? Also to be honest BBS's gameplay is something you need to learn to understand. Yes you level up your abilities, but maxing them out is not enough. You also need to learn the attack patterns of the bosses you encounter and take advantage of their openings to fell them. BBS is one of the few games in the series where mash x to win just doesn't work out. Especially so if you don't just pick a lower difficulty. Beyond that the capabilities of the PSP were not exactly any lesser than the PS2's, in fact being somewhere above that of the PS2 and bellow that of the PS3. And lastly 99 is the max level in almost every RPG, but the maximum level you should need to be for most RPGs regardless in order to 100% them is Level 50. BBS falls well into that range.
