Thanks for the heads up. That looks like a steal at $1.99. I was sorta in the same boat as you except on Cro-Mag Rally. I got it at $5 or $6, but then it fell to $1.99. I think a lot of developers are finding out that the sales of apps extremely increases when you get below $5.
It takes a lot of pre-sale confidence to plop down more than that on an app. I did that for Scrabble (awesome) weeks ago and X-Plane last night. I used to like flight sims back in the day on my PCs, but I haven't touched them in a long time. X-Plane looks decent, but I think I'll have to do some reading to figure it all out. Not to get too off track, but I haven't seen a flying game of any sort to top "Top Gun: Fire at Will." If just the flying aspects of that game could be replicated, it would be awesome.
