Perdition's Gate full version only maps

What maps beyond Map11 are actually a good play, if there are any? I always recall reading the demo is best. But is the rest really a turd, even if I manage to get it legally?

I rate it pretty highly, and consider it part of Final Doom due to its history

It's pretty good. You'd be missing out on the kickass ancients levels in the second episode (a pretty good theme). Some of the Hell levels are really short but it's all good as long as you go in expecting short to medium size maps.

I own both Perdition's Gate and Hell 2 Pay,full versions,legally.I can tell you they are both worth playing.You'd be missing out by not checking them both out.I highly recommend them.
