I'm a big AC and Glitch fan. I reckon it would do good if the Glitch team played AC a little to get a feel for the stuff it has going for it.
Things AC has that I like - the interaction with the AI characters is more 'realistic'. This is my opinion of course, but they have less 'outlandish' things to say and so I can relate. I don't bother talking to AI creatures much in glitch since the stories are long winded and meaningless.
Fishing... who doesn't like fishing! In AC, fishing is a hugely cool thing. As is making snowmen and catching insects
Seasons - real time seasons is uber cool in AC.
Anyone else think of AC stuff that they would love to see in glitch? I'd really like to see a 3d environment evolve in glitch, though it would be too big for a browser based game atm I think.
