Temple of Elemental Evil
A few days ago I saw on TV a program about reviews of PC games, and they reviewed Temple of Elemental Evil. I didn't understand much (can't still speak much of Finnish yet...

), except that it got an average mark 8/10 and I got that the mark was lowered due to several engine bugs.
It looks like it's very similar to the Baldur's Gate series, which I quite liked. So, has anybody already played it through? I have no idea when it actually came out, so maybe someone might have already finished it!
Is it based on 3.0 rules entirely or 3.5? What are any differences worth of note? I would be glad if it was either 3.0 or 3.5 compliant, but I guess there must be something twisted, like in Neverwinter Nights.
Are there any hard restrictions? For example, I am quite sure that Leadership doesn't exist, but what about familiars/animal companions?
One of the limits of BG's series was that too often there was just a way to open a door, get an item or kill a monster... despite the fact that 3rd edition rules offer countless of options in "live" RPGing. Does ToEE has this sadness still? For example, BG had some many times this kind of situation: a closed door to a secret room, but no way to open it even with a top-skilled rogue or with the most powerful spell, or to smash it with the strongest creature; no way, unless you go through the subplot and find the exact item that magically opens the door.
