OMG they took down some of the first demos and put them up with these TEMPORARY demos? LOL, Nintendo
I think Brain Age, BA2, Flash Focus, and Crosswords are the only permanent ones. The rest seem to change on a weekly basis.
Iron Man is a kinda cool idea: it's like a 360-degree SHMUP where you can fly and shoot in different directions and following arrows to destroy objectives. The hit detection is a bit wonky, enemies take way too many shots to kill, and there's no variety.
Eco-Creatures is neat too, but the controls for switching between your "commander" and units are distinguished mentally-challenged and confusing. The demo tutorial battle was simple enough that my units could just follow me around and auto-attack most enemies, but I can see how it would ruin the bigger later battles.
Best game on there is probably Apollo Justice, but I already own it so no point in that, just like last week with Ninja Gaiden.
Spiderwick is supposed to be a surprisingly good RPG for a licensed game.
