Not a bad idea, but I would leave out demo's and just put in ~3-10 quality mini games. An advantage would be that you could have the advantages of working in a team without the disadvantages; by letting each teammember be responsible for their own game but between share in all the testing, knowledge, bug checking and maybe even assets etc. I would be interested in such a form.

(atm personally I think I haven't released anything notable yet, but I am working on something more promising that I could show later as portfolio work, not to sound to serious though )

ps: demo's could ofcourse be added a bonus / sneak peak like in some old games (= free marketing for the makers of it).
