I can relate to that. Even though I consider myself a hardcore gamer, I really only enjoy putting in massive amounts of work in certain games (e.g. Super Stardust HD). When I play a game I'm looking for one of two things depending on my mood; when I'm worn out after a long day at work and I just want to relax, I'll throw in Burnout Paradise and just drive fast, but on weekends when I have more time, I will spend hours playing Killzone 2 or trying to get 100% on Metroid Prime 3. Of course, the game still has to be fun. If a game isn't fun it doesn't matter how hard or easy it is, I'm not going to play it. That's why I think that having a "demo mode" is a good idea (at least for Nintendo) because if you want to experience the challenge (if that's what makes the game fun for you) then you can. On the other hand, if you just want to relax and enjoy the game world you can do that as well.
