The bit I really don't want in the game is any 'true RPG' like mechanics. Gun upgrades is as RPG as RE9 needs to get.
Definitely not endless collectables and crafting / stats. I'd like a game, not a work simulator!
If done right I would not mind.
All depends if done right and the length of the game. If the game is going to be similar length as other resi games then no point in such things.
But yeah, I can't see it personally. It will likely be similar to RE8 I would imagine.
Personally I was very happy with what they had in RE2. I just wanted to see that slightly improved. I said it many times but would it have killed them to expand on what the original RE2 did and have some interaction between Claire and Leon playthrough? I remember being able to leave her the machine gun or using it. That kind of thing expanded I would have loved to see.
