Does sequel potential impact purchase decisions?

So Alpha Protocol came out a few weeks back. Reviews have been moderate, but I’ve heard more than one person say that in spite of some jankiness, they were still having fun with the game.

I was on the fence about getting it, figuring I would eventually but waiting on a good sale (after all, I’m neck deep in Steam games after the big 4th of July sale they had). Then, earlier this week, Sega announced that because sales of Alpha Protocol weren’t very good, they wouldn’t be creating any kind of a sequel for it. It was to be a 1 game intellectual property (IP).

I was surprised to find that this announcement dampened my interest in the existing game. I’m really not sure why; I haven’t taken the time to dig through my own psyche to figure it out. I mean, as far as I know Alpha Protocol stands along as a cohesive whole; no sequel is needed to complete the narrative or anything.

For the purposes of this post, why I feel the way I do isn’t really relevant. What’s interesting to me is just the fact that I felt that way: that by announcing there would be no sequel, Sega cost themselves a sale (or at least, delayed it…now I’ll wait for it to be a $5-$10 game on Steam before trying it).

And I was wondering if this is just another case where I’m way out on the lunatic fringe, or if anyone else felt this same way. So here’s today’s question:

Do you think that knowing a company has given up on a new IP would adversely impact your decision to buy the game that debuted the IP?
