I'm quite surprised that ADOM 1&2 made it this high, given the fact that no new version of 1 is publicly available (donators only, to the best of my knowledge), and 2 doesn't yet seem good enough to me, IMHO. I'd say that people are mostly excited about the development going on after such a long hiatus.
ToME is no surprise for me. DarkGod is really spamming (in my eyes, not a bad thing per se), but the development of what I call a really good game made huge progress even during those few months I'm playing it. The excitement part from a final V1 being very very close most likely plays a part here as well, but I must give credit to DarkGod for his work.
The same goes for DCSS. It has a well-established positin in the RL world, ever-ongoing development, two tourneys per year. And, to put it simple, for me it's currently the best roguelike around.
I would say that AliensRL are simply not established and known enough yet to score big in this survey. It's only IMHO, but it seems to me that there's really a small number of players who didn't get to AliensRL through DoomRL, and some may say "nah, just some DoomRL clone in a different setting". Understandable for me, as well as it's understandable for me that Kornel feels sad about it.
And DoomRL as number 8? I certainly find this a reason to conrgatulate Kornel :).
