I have two problems with the proposed solution. First of all, this giving a general definition of what's a game, seems unnecessarily complex to me. But more importantly, it broadens the range of accepted games too much. Not that I'm personally against it, but I think we should do it gradually, in order to avoid unexpected situations that we may not want to get. I think we need to have a clearer vision of what we want to accept and what we don't want to.
For me, the issue is not about what games we want to accept, but about what movies. Because many games may be applicable only for specific goals, like full-completion or maximum score, but not for fastest-completion. Also, I think that the community still doesn't want to start accepting completely trivial movies, like Rhythm games, for which there is not even the need for TASing tools in order to produce a perfect movie, and the difference wouldn't be noticeable not only when watching the movie, but not even while making it.
So my conclusion is that a movie should be acceptable if there is a minimum requirement of basic TASing techniques in order to make a movie. This would means that submissions like Duck Hunt
and all Bowling games would become acceptable, while a Desert Bus
movie would remain unacceptable due to the low effort required for playing it (beside physical stamina, I guess). In any case, I want to make sure that the community is happy with it.
