I have a pretty beefy system, but the game is running decently at 1600x1200 with every feature maxed out. So I would assume it is possible to get ok performance on a medium end system with the right settings. Other things...
- Run speed is slow, but will increase as you raise your althetics skill. There are also magic items, spells, etc. You can double your runspeed right off the bat by selecting the sign of the horse or some such.
- Game is very similiar to Daggerfall, but much more stable. Not perfectly stable, but very good.
- If you don't like walking between towns, you don't have to, but this is where the meat of the game is to me. The countryside is literally crawling with dungeons, quests, beasts, etc. Keep in mind as a Daggerfall game, there are no safety nets. You can create a lvl 1 character and walk right into a dragon's den. You will probably have a bad feeling before you do, but the game will allow you to do almost anything. Save often (in series to so that your only save wasn't 2.3 seconds before a nasty beastie sweeps from the sky and guts you for dinner. Forgot that lesson from Daggerfall, ouch)
- The graphics are simply awesome. The best I have ever seen. The water effect alone is worth buying the game (and needed hardware) for. It gets better the longer you look at it and play around with it.... Some downpoints though. Naked characters look crappy, very visible seams between arms and torso, etc. The shadows of characters also suck. They don't account for what the character is wearing, you always see a 'naked' shadow.
