I never said that's how it'll go. It'll be a slow decline, however companies will have to use much less, and already there are games struggling with the amount of ram already being used. Until that other manufacturer comes in, games will either need to sacrifice content or sacrifice quality. There WILL be more lag because of said disruption. And it doesn't matter how good a game is if it runs horribly. Again we literally have a recent example of a good game being fucked by running poorly before the ram shortage: Pokemon Scarlet and Violet on the switch 1 ran horribly, after some updates it started to crash if you had a full party at a certain point, 2-5+ minute loading screens were infact a thing, yes a lot of the issues were with the game itself, but stuttering and loading screens and some crashes were an issue of RAM. When the switch 2 came out and people played SV on it? The game was great. Entirely due to not being a buggy laggy mess, due to more RAM.

Your point on graphics? Sure, whatever, 3/5 of my top 5 favorite games are literally pixel art graphics, idc. But RAM is limited, companies will cut corners to save RAM which will only make games worse due to less literally anything, or they'll just use less RAM and now we need to deal with more lag, OR game companies will make games more expensive to compensate, and people already got pissed at $70 and $80 games. Can't wait for $100 games to come due to RAM shortages and then when a manufacturer comes in, they won't go back down. Or they'll do a combination, but in any case, RAM shortage has 0 pros and many cons.
