I just recently realised that the chessbase software is available on Steam, which would seem normal to me if it wasn't almost half the price compared to the version on the official website. I have chessbase 16 and chessbase 17 is on offer but I don't want to pay for a cut-down version, do you know if there is a difference?
My understanding is not much of anything unless you are a power user. I do believe there are issues if you intend to use things like the Mega Database etc. ultimately it's just a licensing thing.
In all honesty I wouldn't generally recommend Chessbase. This is from someone who owns it, uses it extensively, has a dedicated server just doing analysis.
There is nothing in Chessbase that something like SCID cannot do for average user.
