You have to include gameplay. Otherwise people wonder why you don't "make a film".
Haha. We've hear that reaction to our work regularly. As if there's only two things you can do with a computer: games or films. You don't even need imagination to realize that this is untrue. Since the person making the remark is probably using a computer and software that is neither a game or a film.
Indeed. It is very interesting to see how the video game medium has locked itself in a very tight room. When you try and pitch or explain an idea without any gameplay, an experience that isn't really a "game", people don't understand you. Why would you want to do that? As if we have to limit ourselves to only creating systematic games.
@ Got at play: I'll probably release my latest game/prototype on my website in a week or so. It's about thoughts in an elevator. It's about taking an elevator ride to work at 8 AM and what you mind is thinking of during that short time =)
