Well out of curiosity, with the changes in AI card use that phase 14 brought I decided to beat challenge 2 again. So on Sunday I sat down to play it. I was wondering how much harder/easier it would be now that things would be a bit different. I didn't have a lot of time so I didn't watch any turns play out (skip to end on all turns), but I did manage to beat it in 39 turns (had I had more time and watched turns I probably could have trimmed a couple turns off atleast). This seems not that much different from how it was before since I beat the previous version once, although didn't get to finish it due to time constraint, and I'd wager it was going to take about the same amount of turns that time I beat it.
I was thinking since one AI wasn't using all the cards abandons might not be as effective and predicting the AI might be harder. That they might also have more attacking power on the areas you don't block off, but it didn't seem too bad. Maybe slightly harder. Still quite beatable though, incase anyone was wondering. I'm not sure what it takes to get a score as low as ~26 turns though as I've never beat it that quickly.
The challenge is pretty time consuming and a way to save and resume play on it would be nice. As it seems to take ~2 hours to play it in a rush.
Are we ever going to see a challenge 3 or perhaps you're waiting to see what people come up with on that offer to make your own you tossed out at some point?
