Ignoring the lack of updates if the game is buggy, games back then were also more focused on quality and make gamers replay the game with unlockable features based on skills, not money. I can’t count the number of times I played Metal Gear Solid games over and over to unlock new features playing the hardest difficulty and with handicap features, and also to find Easter eggs. Speaking of Easter eggs, you’d lose a number of hours exploring every nook and cranny finding them!
People talk about the original Pokemon games being buggy to all heck. And yeah, sure, but that’s what makes them fun. They’ll also never crash just from normal gameplay.
The newest Pokemon games will lag and stutter, and can crash from normal gameplay. Maybe even corrupt your save data.
Thankfully we have cloud saves to protect us now… except Nintendo disabled it for Pokemon games because they’re jerks.
