I gotta give it to the first two Ys games.
Before I played it, I heard older gamers on the internet constantly praise these games. Seeing how I really dig Action-RPGs from that era (Secret of Mana, Zelda: LttP, Beyond Oasis), I tried Ys I & II on a Turbo-CD emulator.
This was three years ago, but I remember really not liking the game. The combat system, or lack thereof, is awful. Simply running into enemies is not fun, and gets tedious real fast.
The dungeon design is really boring. And the puzzle are ridiculous.
The only redeeming qualities of the game is the boss fights, because there at least you get neat bullet-hell style projectiles you can dodge. And maybe the presentation, seeing how I have a soft spot for how late-80s anime looks. That's about it.
