The games you want to play, GTA5 or RDR2, are both games of this generation. Even with the next PS5 or XSX, the gameplay and graphics won't improve much. So far, you haven't even played GTA5, which means you're not a PC player. You probably haven't played a lot of great games in this generation, so it's a good idea to get your hands on this generation's console. Both the PS4 and XOX are at historically low prices due to upcoming releases, and both used and digital versions of the game are extremely low. This time period can be played with the lowest price to do long this generation game.
