Eh. I knew one a you guys was going to show up lol
My opinion is that there are some games that stand up above the rest, are well designed and well implemented, etc etc, and I have no qualms with calling those perfect.
You can do everything. It has permadeath. It is very difficult. It can take several months of gameplay before you win. Even when you are maxed out on levels and have killed hundreds of every monster, you can still get to the end and die.
Best Game Ever. But not perfect.
