That's the other thing that's been niggling me about this. I knew Hellgate was a diablo-esqe game, i.e it's SP with MP content and design. So when people turn around and start calling it a F2P MMO, I don't really even know how to react to it. I buy SP games readily. I don't buy or play MMOs readily, especially F2P ones because I generally don't like the designs, the artificial limitations or how much you have to invest in MMOs just to get settled and see if it will be worth it long-term.
So HG seems like it has enough red flag issues for me to stay away from it. More than enough, really. If it bothers some people that others wanted to opine about it, sorry. But this is a gaming forum for opinions, not hive-mind agreement.
As for what full-fledged MMOs do.....I feel like WoW is pretty honest. Get an time-unlimited demo capped at Level 20, pay a sub for the full game. That makes sense to me in the context of an MMO. Using a downloader client to get a 6 gig game that is SP with MP trappings, and having to pay beyond Chapter 2, just sounds like an extension of the wonky business thinking that made people go "Uh no" in the first place.
Put yet another way....If Diablo 3 released tomorrow and said "You download the whole game and then pay $60 to play beyond Act I" I'd be asking them the same question. "Why didn't you guys just do a demo?"
