Persona 4. It's still a good game, but it tried to mess with P3's battle-system, and, I've said this before, P3's battle system was a massive dick to you and the enemy. In P4, though, with the whole Down>Dizzy thing, instead of P3 missing the first-step, enemies get a major advantage.
And 40% of the time, I found myself really underleveled. I spent an entire in-game-week leveling, and I still had bloody trouble. Did really like the story, setting, and, oh god.. the music.. (foaming from mouth with unhinged glee)
Quest For Glory 3
There's me, a little youngster, I just finished Quest for Glory 1&2 on my old family DOS. I get a used copy of 3. Yah I say, only to realise, it's... well, shit. Annoying characters - I didn't like the Tarnans, the Simbani, or the Leopard men - the only characters I liked were the non-factioned characters, and even then, they don't appear to much, and it was way too text/dialouge based. How boring.
Again, not bad, but not good compared to prequels.
