The complaints? In NES version, I thought the game was horribly slow. Walking around in dungeons is slow (feels a lot slower than in FF1 and FF3j for some reason even though even those games don't have Dash), and fighting is very slow, especially when casting spells on multiple targets, like your party or all enemies. I almost fell asleep during one dungeon, and after that, I used the emulator's fast forward option to turn off frame limits while walking in dungeons or in battles, after giving commands.

I didn't have a problem with how weapons or general stats level up or down. The problem with NES, WSC and PSX versions is how slowly magic spells level up. You need to cast a spell 50 times for them to gain a level, there's 16 levels and you need to cast those spells during every battle to have even some chance of raising them. I think the best spell I was able to get on NES version was Cure10, the rest were on levels 1-5 or so.

DJzen, have you played the DoS version? I've tried it for about 15 minutes, and things seem to level up faster there. Do you think the changes in the battle system make the gameplay smoother, or is it just as enjoyable as FF2 NES/WSC/PSX, or do you think it totally waters down the system and ruins it?
