How is that not a comparison? That's what you pretty much did. On top of that, MK is already a long running franchise, and both MK and IJ are two separated franchises that come every 4 years each, and there are players who play only one of them at a time. I see players on RZA's Streams like Daphanate and Nausea who keep playing MKX on a high level but barely touch IJ2 if at all, and just this past weekend at KIT there was an MKX tourney that was on stream with a bunch of top players like Sonic Fox and Forever King, in addition to IJ2. Just because WB doesn't allow NRS to support the games after 2 years that doesn't indicate anything, and even 2 years is still more then the one year that COD games have, as not only the support ends for those games after just one year, but the next game in the same franchise is released. That's not the case with MK11, a game in one franchise that will be released 2 years after IJ2, a game from another franchise. Same publisher and same developer, but two separated franchises still.
And BTW, back in Midway, Ed Boon made only MK games 90% of the time (except the Grid) and for the most part they came once every one year or two years, and even then they weren't consumer-only products. So how they can be consumer-only products now?
You don't want to drop the game after 2 years? Then just don't drop them, plain and simple. Keep playing what you wanna keep playing. I myself play them both right now
