Re: ways to tell if a game is dead
IMO I depends how invested you are in the game. Would you be relieved to see it go? devastated? don't really care? sorry, but you'll move on? Unless it's in the first, or possibly the third, category, I'd wait longer than a couple of weeks. It doesn't take much to disrupt someone's life for that long. Even one issue can do it, and you know how it goes, when things go bad, it's usually more than one thing.
I can remember a period when I was having computer/connection issues. I would get on long enough that I showed as having logged in, but I'd get dropped before I could post, or probably even read. People have ended up in hospital for weeks, computer dies and you may have to wait till payday (or several of them) before you can afford to replace it, kid gets sick and everyone in the house is a zombie for lack of sleep....
