This looks like a raspberry pi clock project, with a Mario theme - it’s not a terrible price if you don’t want to build it yourself (at least I think) - but I doubt you can customize like a self built one.
Also if you make your own you’ll probably get sued, so just don’t sell it I guess lol
I think in Sony’s case a reasonable alternative is to just refund, which is what they’re doing anyways. There’s no way a full refund would not be considered a true option, so I think the Concord side is a bit irrelevant to the primary issue of server owners shutting down servers for old games and keeping the money.
IW4x exists if you want to mod the original MW2 with dedicated servers, been meaning to try it for a while so can’t comment on its popularity
