I think a poll is unnecessary based on current feedback, but we should still contact the Glest Team about that. It would also be nice if we could obtain their download.com account so that Glest could be properly updated there (which claims some 113k downloads) without a nasty duplicate. And of course, to clarify, the name wouldn't be "Glest 4", by the way, but just "Glest", with 4 being the version number.
Perhaps we should have, for now, a "Feature requests" board (that is, a primary board, not a child board)? After all, it would be needed eventually for Glest 4 (as that would obsolete the MG and GAE boards, and would not be some branch, but a full continuation of the original game). I added a poll to decide this.
