I'll go along with that one, and add two related ones: extensive news coverage of their money problems, and/or missing their delivery deadline by a year or more. So far without exception, either one means the same thing: the game will be badly broken (not just incomplete, actually broken) on launch day and will never, ever get fixed.

On an unrelated note, the words "hard core" anywhere in the marketing are also usually enough of a turn-off for me that I lose all interest, because what they usually mean is "PvP with harsh consequences for the losing player," and that's just not my idea of fun.
