If I was you I would make a Warioware type game at the end of it all. Have the option to select any of the games like in a Namco arcade type app but then have a Warioware mode where you play each game for like 10 seconds each to give an overall score. Would be pretty cool if could be made so that 10 seconds (or maybe more) was possible in each game.
This idea has already crossed my mind,
I'm a big fan of the Warioware games.
Sue, she sells sushi, is my variation of a mini game in Bishi Bashi Champ,
and New Year Boom's inspiration is taken from Hypersports.
With 52 game ideas at the end of the year, I'll have lots of things to work with.
