... besides Extraterrestrial Grudge and Inferno Uncovered? Title says it, I'll want some good vanilla WADs for my phone to play PrBoom with, and run on Chocolate Doom with my delightfully SNES-esque Saitek P3000 controller configuration, complete with a weapon switch shift key (Courtesy of JoyToKey).

Also I know of a few good Vanilla WADs, particularly Alien Vendetta, Hell Revealed series, Requiem, Mars War, and so forth, I'll play through these after I beat Doom II and Final Doom for real, and I'll take anything you can throw at me.

Not sure but,

kamasutra. Multiplayer ask for gothicdm (not all maps are good, but they are good anyways).

Notice that vanilla-compatible and PrBoom-compatible are two different things. PrBoom can also run Boom format maps.

And there's a really huge amount of PrBoom-compatible. I will list some, and I'm not sure what map format they are.

Zones of Fear - Megawad with various maps, some of them are epic, some a bit worse.
Scythe 1, 2 - I didn't played it much, but they're megawads, so I list it there.
Community Chest 1, 2, 3 - Played only first one, didn't liked it at all, but some people may like it.
Congestion 1024 - Pretty darn good maps. Loved it.
Speed of Doom - Superior maps.

The Brotherhood of Ruin is in my opinion one of the greatest wads. I'm pretty sure it's vannila compatible (could be wrong) but yeah, any of Kristian Aro's maps are great.[/align]

Do you have Ultimate Doom on there as well? If so, Base Ganymede is an excellent choice. There's also DTWID.

For Doom 2, a good megaWAD would be any of these:

helinhel A decent megawad that seems to have fallen by the wayside.
Cleimos 2 Really good oldschool megawad, ends at the level "Release me", so you can stop playing when you beat that.
Doom Core Starts out easy, but has some really good maps, and I enjoyed it all the way through.
Reviere This is also pretty good, but you might get lost in Tech Towers. The only really bad thing is the horrible intermission texts, heh.
Memento Mori A classic among classics. If you haven't played this, play it first.
Memento Mori 2 If you haven't played this, play it second :P I liked it better than the first.
Revolution! Really good, very Doom 2-ish. Easy but not boring.
Requiem Haven't played in forever, but I remember it being good.
