If you like Doom The Way Id Did serie of mapsets, this will probably be of your liking, as this mapset was release a few years before of the TWID serie began, and its possibly the mapset that give the idea to the original designers and is actually a precursor of the serie.
Wraith made his own version of Ultimate Doom, adressing all the problems the original IWAD has.
Maps are rehashes of the original maps, so even when the maps are similar aesthetically and contextually to the orignals, they are by no means the same, and most have the touch up to difficulty and navigation Wraith thought would make them even better.
The principal change is that most map are interconneted, especially after map E1M5 and all E2, E3 and E4. So its hard for you to get stuck or lost as most on the original maps suffered with deadends and some oneway only sections.
The tweaks to difficulty is apparent as this maps are more challenging than their IWAD counterparts, and that mostly thanks to Wraith more than enough experience on mapping that let him design better enemy encounters and moster placement but still being respectful of the original design of the map.
Another great enhancement is that the boss maps are actually maps and not just an one on one arena anymore. So the added challenge is greatly appreciated in here.
For certain, Wraith made an excellent megawad that not only its faithful to the original school design, it also adresses the problem of the original maps making them even more fun, entertaining and challenging than before.
Why it doesn't win a cacoward and was just a runner-up when there was no vanilla winning mapset that year, it something that totally baffles me.
So for me, this one is the vanilla cacoward winner of that year.
An award it totally deserves.
A really impressive (for the time) remake of Duke Nukem E1L1, with new graphics, sounds and music. Lots of great detailing where the explosions hole and the sloped ceiling/floors are, lots of new textures (including the dancing girl movie at the cinema!), small sectors elevators where the jumping sections are and lots of clever ideas and trickery to emulate the Duke Nukem 3D feel at best under the vanilla limitations (even if i've got a small VPO at cinema area)...
