...Placing a simple time limit on the demo, especially when the maps provided can be pretty easily played to completion within said limit (and you can of course play again if you like), isn't at all out of line or unexpected IMO. The point is to let you see how the game plays so you can decide whether to buy it, not to give you a free day of entertainment.
I really feel I'm a lone one calling in the desert here. So let me get a few points straight:
- Yes we all think that this is a great game, including me
- Yes we all think that 90 min should be enough to show the value of this game, especially because it will give you enough time to finish a few maps.
However, that's not the point: when trying to achieve critical mass with a demo, it's not about the real value but all about PERCIEVED value.
Ironclad/Stardock is aiming to reach a big as possible audience with this game: check Frogboy's vision on marketing in multiple articles.
My thesis: The time limited mechanism decreases the percieved value of the demo and is therefore a less effective marketing tool to get people to buy this game. Even if it turns out that it's actually a more valuable proposition, the percievement is what stops people from playing the demo in the first place.
