>> Should Games go back to cartridges?

[black orb]

I'm not sure if I understand your question, but I'll try anyway. Of course I can't say for certain that playstation 4 cartridges won't fit in playstation 5, but it's a good guess. As technology progresses old cartridges won't have capacity enough to contain new games for new consoles and they may have to make different cartridges for the new consoles. See NES, SNES and N64 for reference. All produced by Nintendo, 3 different cartridges.

>>> If im not wrong the Nintendo DS used to be compatible with the Gameboy Advance carts..

1- My biggest issue with cd/dvd/blu-ray is that those things get ruined too easily (money wasted in the end).

True, cartridges last longer than discs. Although this never happens to me anyway. The last disc of mine that got scratched to death is Tekken 2, and that's 12 or so years ago.

>>> You must be very careful with your games then, personally almost all the games i have bought have become unusable (full of scratches and stuff), and that REALLY piss me off..

No, no and no. Optical discs pretty much have the advantage over everything else thus far.

>>> If someone creates an optical disc thats totally scratch proof, I will agree with you..
(i voted yes)..

You have to be pretty careless to ruin any of them, especially Blu-Ray. Put them back in their case when you're done playing them. Otherwise you're just asking for any damage that may happen to them.

>>> Well, I like to share my games with brothers, friends, etc. and some people like to rent games too, you cant expect that everyone is going to be extremely careful with their games. In the old days (NES/SNES) this was not an issue at all..
