it's like putting a Cube into a Round hole.
Slowdown: This game suffers from horrible slowdown in parties. When magic is being thrown around, Hunters are flying around the screen with sparkles and Rangers are shooting their grenade launchers, this game will slow down to a snails pace. I'm kidding you not, it makes it very unplayable.
Low Resolution: The resolution is decent, the game looks nice still at the low resolution, however the HUD is a little too big. In a 6 player party, a lot of screen real estate is taken up by energy bars.
Online and Offline modes: This game has offline and online modes, HOORAY! So, what's bad about this? If you have an Online save, you'll have to load the game, select offline, where the game will prompt you that it needs to restart and load the offline gamesave to continue. This has to be the most ridiculous save system I've ever come across. Thanks for wasting my time sonic team.
So this game was designed for PC and PS2, right? Here's the thing, I don't know what it's meant to be a port of. It's horribly watered down and still runs like junk on the PS2 and on PC it's unoptimised, so you need a hardcore PC to run it properly. However, PC is definitely the clear winner as you won't experience as much slowdown.
