I’m quite surprised at the overwhelming MOAR REPLAY vote. I like CoG games for the same reason I like text adventures, visual novels and role playing games: the chance to participate in a story. As an avid reader, the story is not only my first priority, it is nearly my only.
Don’t get me wrong, I play plenty of normal games with excuse plot (Pokemon comes to mind), but to me, the choose-your-own-adventure games were exciting because it allowed me the chance to engage in the story in a more personal level. It’s a form of role playing, although I don’t view my CoG characters as self-insert, any more than Commander Shepard is my self insert. It’s merely a way to be more absorbed, more emotionally connected to the story.
A game with high replay value can be alot of fun, I would buy it, play it and cherish it. But I won’t be emotionally attached to it, I won’t smile fondly when remembering it, and I won’t be as passionate about it. I will probably have a spreadsheet for it, because I have a spreadsheet for rhythem games, but that’s it. I won’t buy a T-shirt of a match-3 game, no matter how fun (although I hear Candy Crash is crazy popular).
I’m not saying a game needs to be completely linear - but for me, having only two major paths is totally fine, as long as they both have an eqully interseting plot.
To put it another way, I prefer DA2 to DAO (except for those damn enemy waves).
