The thing with VC is it not only came out to critical acclaim in 2008, it was then released on Steam last year to critical acclaim and commercial success. SEGA have already come out and said that sales for Valkyria Chronicles on PC were far beyond their most ambitious expectations. The PC is not exactly a platform lacking in high quality strategy games - a 6 year old Japanese curiosity would have no chance in that market without being genuinely great.

If you don't like it, you don't like it. That's unfortunate, but it also is just because it isn't to your taste. Not because it's somehow overrated due to it's circumstance, like a starving food critic giving a 5* review to the only mouldy bread he could get his hands on.
