I want to nominate Obsidian for Mapper of the Year.
Obsidian is the host of the Abyssal Speedmapping sessions, which was designed to bump up some interest in mapping by lesser known mappers from the Abyss forums. It's advocated by Tango TV, and is done on a pretty regular bi or tri weekly basis, which is only the tip of the iceberg.
While he doesn't have a huge resume of major (well-known) releases, his work is quite remarkable and well-versed a variety of areas. From vanilla tricks, dehacked work, detailing, (Project: Hydra) challenging gameplay, mapping speed, puzzle creation, (Countdown to Extinction) and more, he still flexes himself at all angles, with a share in almost every doomworld community project that pops up, helpful advice in the Doom Editing subforum, writing heartfelt /newstuff reviews, and enduring enthusiasm for new map projects, with nothing but encouraging and motivating things to say, with a side of witty humor, and not even the smallest inkling of snide remarks or ill feelings towards anyone or their mapping styles. (which is a lot more than I can say for myself when I won a MOTY award)
His mapping output is so high and scattered in so many different areas, I'm sure I didn't even list half his work, and I'm embarrassed to admit that I haven't even made the time to play all of his maps. However, I'm very much looking forward to his upcoming project Maskim Xul and I hope he can get it out the door before this year's cacowards and really gets his name out there.
I've always had good experiences talking with him, and working with him. He's very reliable, speedy, and an extraordinary team player, and I think with the right partner or small group, he could certainly deliver something revolutionary. He's got what it takes and I think his skills need to be recognized.
