About three months ago and picked up the basic Descent board game and have been playing it very actively ever since. I've played with the same group, and other groups and we've bounced around with the different players playing each role. The typical person in my group has been playing board/strategy/roleplaying games for at least 20-25 years, is intelligent, and highly, highly competitive.
Needless to say, we've had a lot of fun with Descent and have played through just over 20 games so far. We've been amazed at the balance between the overlord and the players. I am personally undefeated as the OL, but overall our games are about equal between the heroes and the OL in terms of victory/defeat. None of the victories by either side have been by a large margin, almost every game has been decided in 1-2 key rounds.
The extremely well balanced and playtested nature of the game is what I was expecting when we recently introduced all of the expansions (ToI, WoD, and AoD). While we got the campaign rules expansion as well, we aren't using it yet.
We're 12 games in since adding the expansions, and all 12 games have resulted in CRUSHING victories by the overlord. This is true even of the game where the only person in our group with no previous, core-game victories as the OL, was OL.
I see a lot of posts on the forums for various styles of play, and house rules people have come up with to address balance issues (which may in part be susceptible to localized misunderstandings of certain strategies, or even other house rules that create the issues to begin with, or just styles of play and preferences).
However, with all the issues I see, I don't see anything from the game designers. Sure, there are a few small FAQ answers, and issues, but nothing that specifically talks about balance issues. If I buy something that's broken (and my perception of the expansions is that they very much are), I expect the company that produces the product to respond, not the community.
If my car died every time I made a right hand turn, the community telling me that I could, in fact, make three left turns instead isn't helpful.
So where's the official response? Is the official answer that nothing is wrong, or something is but we don't know how to fix it, or maybe a fix is coming? I'm very curious, and it will definately effect my purchasing decisions in the future.
