I owned the Battle.net Edition including expansion on CD, however then I bought it on gog, and now very anti-competitively somehow WarCraft 2 BNE GOG enhanced edition super duper lags, right after Blizzard released their own remastered version, which is highly suspect, and I think it's absolutely fowl play at large for far too long from Blizzard, especially after I supported them again and again, buying nearly their entire catalog multiple times over even duplicates on many different platforms. Very scammy indeed.
