The only reason I found out about H&H was from a recommendation on another forum*, after someone made the following post:
"I used to play a game called "eRepublik"? It's a browser based economics game. I adored that game, played with it from beta, was one of the best in my entire country out of a good few thousand players. There was a statistic for strength which you could increase - once a day - by clicking "train", and I had one of the highest strengths in the entire game. Then the developers introduced a system where, if you used "gold" - a resource you could purchase infinitely with real life money - you could e.g. get triple the strength gain. I immediately quit.
I just signed up to this extremely fun game called "The West". A few minutes in, I thought I'd definitely play it some more. But then, after fishing in a stream, I ran out of "energy". And I was immediately prompted: "You have no energy. Wait 8 hours. Alternatively, buy all your energy back now, for only $4.99!!".
Just pathetic."
I agreed completely. See, I find that stuff like this absolutely destroys games from the core, at least for me. The knowledge that, you can use all your intelligence and all your effort, but someone will always just be able to buy their way past you.
On the other hand, there is a subscription based system. For example, Runescape. You've probably heard of it, and I used to adore it, but you simply pay a fixed fee, a month, to play the game. I guess games like WoW also use this system. So please, game devs, if you start thinking big and want to properly finance the game, use the latter, and not the former.
On a side note, does anyone know any good browser-based text games (you know the type, like OGame, The West, Hobo Wars, PBG) which don't have the "pay to be good" system? I would love to try it.
