Well, the early Kingdom Hearts coming out today (on Xbox) do have an impressive number of achievements. I was reading this morning they have 197 achievements worth 4000 points in that game collection.
I already played through the first one though. Not doing that again. And I tried playing through the second one but lost interest half-way through it. The combat got too hard.
One piece of advice if you’re going to play the series on Hard like I did: when you start the game, pick the shield. I picked it on accident the first time through that game, and it turned out to be perfect. Next time I tried playing through the game, I picked something else and it was a nightmare. Way too hard.
