Same, after I beat the game I delete or wait for DLC! There are some games I may make 2 saves so I can see both endings at once (good and bad endings). Dark Souls I may start some of New Game + just to see some differences and still use my stronger weapons. After a day or two I just move on the next game
But
I am currently playing Nier Automota and I am going to beat it 3x. I ain’t going any further than that. Each play through you get a new character. There are 27 Endings (one for each letter and I think one extra 27th). The endings A - E are the true endings, all the others are jokes/ I know this game is long and fun, so it will hold me for the summer (or at least one more month)
Last night while playing Nier Automota I lost all my good leveled up chips after dying twice and not getting my body on time. Time to Farm and Grind today :-(
