As a big GTA-head I want to share one of my favorite retarded Sony+Microsoft moments involving IV:
Originally GTA IV was going to be a PS3 (timed) exclusive, which would've massively bumped up that game's launch. Microsoft not only spent 75 million to ensure it came to Xbox, not even exclusively just concurrent with the PS3 version, but that ended up getting the whole game delayed to work on releasing both versions simultaneously and the PS3 version ended up being the worse performing version both financially and technically
However that ended up being a massive L for Microsoft because they put up a good chunk of this money to fund the Episodes TLAD and TBOGT, to make them temporary exclusives, but because they were exclusive to Xbox for a year they ended up performing poorly and Rockstar didnt do singleplayer DLC after Undead Nightmare partially because this deal made them lose money they wouldve made if the DLCs were multiplat
