This game is fantastic. It got panned by critics when it was first released because it was extremely buggy and the graphics were less than stellar. But 8 or 10 months after its release (something like that), the devs overhauled the graphics and fixed all the bugs, then released an expansion (which is included here) that was almost as long as the original game...each part takes around 50 hours if you do all there is to do, for a total of over 100 hours of gameplay. If you rush through the main story, you could probably finish it faster, but in a game like this, why would you want to? We play these kinds of games (literally ROLE PLAYING games) to immerse ourselves in the world the devs have created...and this one does not disappoint. The extra time the devs spent polishing the game up were well worth it. I didn't play it when it was originally released, so this was my first experience with it, and I'm quite impressed. The graphics actually look pretty darn good. Rich detail throughout, and very few areas look less-than-completely polished. The character animations aren't the strong suit here, but they are on par with most other RPGs, and better than many.
The main story is pretty good, for a game like this (which, for games based on story, are frequently pretty lame, sadly). The side quests are decent...fairly standard RPG fare, but they take you into some pretty cool environments, which are all fairly well developed.
It's not perfect, however. My biggest gripe (and, frankly, one of my only ones) is with the controls. Generally, they're fine, but if you want to highlight something/someone (like when you want to talk with someone), you have to get a tiny little cursor perfectly on them before you can push a button to initiate a conversation (or pick up an item, or whatever). It's extremely frustrating, and even after many, many hours of play, it doesn't get much less frustrating.
That being said, that really is one of my few gripes. The gameplay is, by and large, quite fun, with varying and unique enemies and environments. The game really comes into its own, though, when it allows you to take dragon form...something that unfortunately doesn't happen (except once, briefly) until quite far into the game. This is a shame, because it's the best part of the game. Flying around as a dragon is loads of fun, and the flying controls are excellent. Insofar as such is possible, I really felt like a dragon flying around, spinning through the air and breathing fire. Very cool. I just wish they had introduced this far earlier in the game, and (thus) allowed for a lot more time spent as a dragon. Note to developers: being a dragon is cool. When you pull it off well, make it a large portion of the game!
Overall, this game is very fun, and highly recommended. I didn't play it when it was first released (largely due to the bad reviews), but the devs have clearly fixed the vast majority of these issues. A quick search of reviews for the updated version shows that most reviewers love the new version, and rightly so. It's awesome. The expansion, which again is included here, is just as high quality as the original campaign, and for the cost here, the package is an incredible value. Highly recommended!
