Is xenoverse really that good? I might...just might have to buy a dragon ball z game again since budokai 3. It's been a while but congrats on the success. We will see...
If you like DBZ at all it shouldn't be missed. The core gameplay is a lot of fun, the story is surprisingly engaging, and character creation/building is an utter blast. It's not perfect, but the foundation for an absolute classic is there.
Plus the PC port is good, which is always a pleasant surprise.
How reliable are the Steamspy statistics anyways?
The Ars article that spawned it only claimed "A few Steam developers have also been willing to share their own sales data with us off the record" and that's kinda it.
SteamSpy is an accurate estimation. Several developers have commented on it, and, IIRC, their official numbers have been within the margin of error for the most part. There are even developers requesting to be omitted because they don't want the sales numbers published. With a variety of sorting and filtering options and regular polling, SteamSpy will only get better.
The only thing that throws it for a loop is free weekends, which will skew results for some months afterwards. But fortunately the results will make mention of this with a big fat asterisk.
