Game List: by Time Required, by Difficulty etc?

[mtl]

I've played 3 different types of games here: Puerto Rico, Takenoko, and Can't Stop in that order.
I really like the Game List on BGA, giving us game suggestions, etc but I thought it would be nice if it would also be in order of difficulty and order of time allocation.

ie if I only have a few minutes to play, I know which game I should pick, it also tells me which games are less complicated to learn from scratch etc

what do you think?

oh ops : it does say medium and long length games but maybe we could add a short length game list? or are those considered casual? hmm
