Who knows... might be wave the Queen's Gambit caused and chess has valued higher :)
I like chess (I am not good at all, but). I played the MSDOS battle chess sometime in the 90s and its animations really blew my mind... and still they do! Same as Prince of Persia: considering the programing and tech limitations (HDD space, video memory, resolution, cpu speed, speaker!/sound cards, laplink cable!, hardware standards!...) they were true achievements I've seen counted times in my life. To keep it short: Let me tag both games as progress.
Fast Forward to 2017 when I took GOG seriously: I vaguely remember searching for it because during this decades have played another chess vgames and to me the place/podium of BC is on the past: Pure nostalgia, history/teaching, use/adapt/challenge on limited hardware.
Under those circumstances, I would shell out happily the 10 bucks for BC (that specific one: I tried the others out of their periods and really did not impress me, sorry!) in recognition of:
-The progress provided to the computer industry (programming, vgames, hardware) and its legacy!
-The work during this decades to make it run
-Its a real finished & quality product: No BS of DLCs/IgnoredBugs/EarlyAccess/OnlineScams... Yes: its weak point is the resolution & its engine been crushed by the current ones but...
-Chess is a game you can play endlessly and don't age!: the rules are the same, the mechanics stand
-Chess is strategy in its more beautiful form :) and there is a point in every player development where graphics/shape of the pieces/board does not matter at all: what matters is how challenging/entertaining is your opponent!
By the way, I would also happily pay a high price tag for a Chess Master running on Win7-8-10 if GOG brings it alive again: Its tutorials are superb! ... Haven't found any other vchess game as complete as CM
