I know, I know. Suggestions from gamers are invariably stupid and shortsighted BS. Bear with me though and just look at them.

You might not have the latitude or budget to do anything to this game since you already released it on XBLA but - I think there's some things you could do that would really pull people in.

Anyhow, onto my narcissistic blathering :

1) I should be able to 'tune' my little invader spirits
please allow me to tell them what spells or moves to use more often. give them a weight or something. A priority number would be fine. Give them some simple patterns to follow - like FFIV rules. anything.
2) I want to see the fights my invaders were in
pretty simple, no? I would love to see a replay of my little offspring killing the deserving.
3) pokemon style invader vs invader fights.
stupid idea but I'd love to have my invader fight other people's invaders, for some reason
4) automated 'armies' of invader spirits fighting
I just had this incredibly dumb idea that I love. a battlefield populated with nothing but our little invader spirits that has a daily battle that we can watch the video of and that our own little dudes performances are rated for.
5) "ladder fights" of our little invader spirits.
like the old KOTH code wars - a ladder where each invader spirit fights every other one on the list and then gets ranked for win/loss.

like I said, stupid ideas but I really felt the need to ejaculate them here.

thanks for that
