Once you get past a certain point fairly early on you can pretty much go anywhere (a few areas are still sealed off until you get to them in the main story however). There are no horses in the game. There is non-aggressive wildlife like deer and rabbits.
The GoG version doesn't have anything removed really but the selection of user-made pawns is limited since there is no crossplay with steam.It also doesn't seem to work in some aspects but I found the offline pre-generated pawns to suit my purposes just fine.
The game is a little bit grindy - but I didn't mind too much since it was so much fun to kill things. Inventory can be a pain but I just speedrun to kill the final dragon whenever I needed decent equipment.
Getting the best equipment is ultra grindy and may not even be possible in the GoG version - killing the true Ur-Dragon requires a lot of people playing at once and GoG doesn't seem to have those numbers. I don't even know if it works properly - I tried fighting the offline version and got my ass kicked so I never even bothered to fight the far stronger true version. It's all extra stuff and not necessary anyways.
