I'm still wary. The press I've read on this game has been largely positive, but I played many of these games before, and they usually have two kinds of problems. The first is a limited library--the object you need for your ultra cool creative plan doesn't exist in the game. "Error, not recognized," utterly destroys the sense of freedom these games are built upon. The second is the limited functionality/interactions of objects you summon. The game may let me conjure a ray gun to shoot down enemies with a beam of energy, but that is all the developers thought for it to do. I can't use the energy beam to light a camp fire. Ultimately, rather than being "How creative can you be to solve this puzzle," these types of games turn into "Did you happen to think in the exact same context as the developers? No, too bad, doesn't work."
Maybe this camp will be better. Maybe everything will be so highly intuitive that you have to intentionally try to break the game before you are told "No, you can't do that." I'm cautiously optimistic.
