Wizards of the Coast is the main company that handles Dungeons & Dragons, Magic the gathering and other games.
In my opinion Strixhaven was a piss poor product. The OGL scandal and the subsequent dribble of constant controversy from WotC that has you saying, "Its been a week, wonder what WotC is doing to alienate gamers lately" is the reason for 2 stars. They put D&D in creative commons so guess what D&D belongs to us who truly love it and we are no longer beholden to a big corporation that has no clue and no idea what it is doing.
The company gets a lot of crap from some gamers but in the end they handle D&D one of the most loved games around. I also will note that as a D&D player that plays 3.5 they do tend to once they move to a new edition, they abandon the old one. Giving up on making new content for it, thus my 3 star review.
