>>44187833Imagine a pair of new versions of Colo and XD. Both share an updated battle system, and what you do in Colo shows up in XD. Just about all fully-evolved (And some prevos) non-legendary Pokemon from Gens I-III (Plus the Gen IV crossgen evos, including a few babies) show up somewhere in either of them, but very few normally show up in both.
Both have heavily buffed and expanded plots, and after the main game of Colo you can do a big new quest, which includes purifying all Pokemon you've found, and ends with Wes disappearing searching for what is hinted to be Ho-oh.
Then in the new XD, you have tons of new stuff, too, with the Pokemon you can normally capture rounding out the list of fully-evolved 'mons. But among the new or expanded areas from Colo, you can go through a bunch of quests to get all of Wes' purified shadow Pokemon, which he seemed to give away.
In the end, there in a new quest, and Wes is the "surprise" villain, and it's cool and I don't really know any further than that.
I just think it'd be realy neat if you could get Wes' pure Pokemon, and if you hadn't snagged 'em all and purified 'em all as Wes, they don't show up in XD.
