Ratchet & Clank is actually a reboot as the series is being "rebooted" and they are not just remaking a single game here. There is even a movie for it that followed shortly after it's release and we can most likely see more of it in the future to come. A remake would be if they just remade 1 game and that be the end of it.
I had to stop playing Fallout 4 because there was just too much walking...
I suspect a lot more games to be coming out in an episodic format in the future. Now we can still buy episodic games for a normal price (where you buy the full game for say $60) but I believe that in the future the option to buy the game in full will be removed and each episode will need to be purchased, which could lead up to $100 per player vs the current $60 price tag
