Also you can absolutely still play CSGO if you want.
Yeah if you want to use an obscure feature like steam console to get the latest verison or using beta to get an older verison, instead of you know releasing a fucking separate steamid for a game that is reporting itself as a "Sequel" and don't get me started with them piggy backing off of CSGO's reviews. Imagine if some game like Supreme Commander did that bullshit. Where you had the beloved first game and welp with the sequel out we should all replace it so it can use the same reviews even though the 2nd game was universally panned. This is so assbackwards and noone should stand up for this behavior. Valve is mostly awesome but they botched this release and did it in one of the worst ways possible. People fucking play CS 1.6 and Source still would it be right if they were just disappeared as well but able to be pulled up via download some obscure Steam depot. Hell I have an even better one Half life 1, very loved game but Half Life 1 Source an apparently upgrade that was fucking garbage at launch and still garbage to this day. Would it have been right for Valve to say if you bought the default way to play Half life 1 now is via source only. Noone with a working brain would want that.
