I've ordered the 5200 version from AtariAge and ordered a 5200 off eBay (neither of which have arrived yet, but waiting...) With the way my life usually works, that means the XE version will come out right afterward... (hint hint).
Feel free to write a review in the AA store after you've played it a bit. Unless you hate it.
I left Adventure II XE alone for many months, wow where has the time gone. I was busy doing other things, and as I get older I seem to have less energy and drive than I used to. However, lately with the earlier nights and colder weather I have more free time to stay in and code away, and I assure everyone, I am very interested in finishing the game so I can move on to other projects. I will post another update after this long holiday weekend to let you know what kind of progress I've made!
