GOG.com: Ultima 7 The Complete Edition features some major changes to the Ultima formula, including the classic grid format and player movement.
It also adds real-time fighting, with party members that are controlled by AI. Vythonaut: Controlled you say? Where's the control? I remember most battles were completely out of control... Oh boy, good luck with this AI and its party members; It can and *will* drive you mad at times!
That said, U7 is still one of the best cRPGs - the interactivity is nuts and the game is a must-play for every cRPG fan out there. Speaking of interactivity, the excellent Divinity: Original Sin showed us how it's done in modern gaming. It's no pre-requisite for a cRPG to be good, but when it does elevate the gameworld when it's done right.
Actually, I would say that the battle system is crucial to a CRPG, and having that be completely botched is enough to say that not only is Ultima 7 not one of the best CRPGs, it's actually one of the worst. (At least it isn't as bad as the garbage that is Ultima 5 NES.)
It also doesn't help that the game has some other issues, including:
* The inventory system is atrocious, and in particular is significantly worse than in past Ultima games.
* You must manually feed your characters when they get hungry. It's not enough to just have the food in your inventory; you need to actually go into it, find a food item, and use it on the hungry character. This forces you to interact with the atrocious inventory more than should be necessary.
The thing is, while having the interactivity might improve an already decent game, you at least need to have the basics down first, and Ultima 7 fails in that regard.
In any case, I would say that Ultima 4-6 are more deserving of the list than the Ultima games that made it on.
(I happen to like Ultima 1-3, but they might be a bit archaic for some, and the mechanics of the early games may seem rather strange.)
