Hopefully Final Fantasy XV
That's funny cause I enjoyed the MH3 demo and it's what got me to get the game, but then I got bored of the game after a few hours and never touched it again.famously
Monster Hunter 3 Ultimate
The Wonderful 101
The SP demo is not that much better as the game needs two levels to kick off and you get into the groove.
How can I be the first one to mention Dead Space? I hated the demo, was flabbergasted when I saw the game at an friends. Amazing game
Hopefully Final Fantasy XV
Would have bought Wonderful 101 if it weren't for the demo. I think I even got it free from a Club Nintendo reward at some point and still haven't played it because of the demo. But I hear all the time on here it was just a really bad demo.
The problem with W101's demo is that it lacks the epic context and the superb story-integrated tutorial of the main game. It's just a bunch of initially awkward fights against some wacky-looking aliens. It's overwhelming in mechanical terms, underwhelming in narrative terms, and it turned a lot of people off before they ever got to experience the full title. I never bothered with the demo and I'm glad for it.
The demo for Hitman Blood Money is the tutorial of the game, which is completely linear and not at all representative of what the rest of the game is. I wonder if many people got turned off by it.
