I have my own reasons about not being a big fan of re0, re5, re7 and re2 2019's inventory systems.
For re0; it's due to hookshot. Despite being a key item; it takes 2 spaces at inventory and it's required multiple times. I dont mind the removal of item boxes, ı found this a nice change of pace but hookshot gets on my nerves.
For re5; it's the quick reload trick. I dont think it belongs to action horror entries. I mean it makes reload upgrades pointless ( Other than unlocking infinite ammo. ) since you're allowed to combine ammo with the weapon from inventory. Not to mention; the game seems to be designed more around online rather than single player and this includes inventory system. And the design looks boring compared to re4's and re6's inventory systems. You also cant combine a g+g mix with another green herb for some reason. I'll give it more benefit though; you can exchange items with partner while in re6; this is only allowed in split screen. ( Meanwhile; this is completely impossible in rerev though partners gave you items at specific points which is rare. )
Re7 is a mixed bag. I like how ethan's watch is shown when you go to inventory and the inventory looks nice, more so than re2 2019's lame looking inventory system. But it still looks boring compared to most of the pre-re4 mainline entries' inventory systems as well as re4 and re6's inventory systems. Though there's no red ( and blue herbs since this game feels like a classic re game in structure and pre-re4 mainline entries have poisonous monsters along with blue herbs. ) herbs and instead there are bottles which arent that interesting. Plus ı dislike the steroids item; it's stupid, especially in not a hero episode.
As for re2 2019; it's very low on my list cause of how lame it looks; especially when compared to re2's inventory system. I've checked ruby of blue's video and the devs apparently planned a different inventory system for the game. It looks so much cooler than the one released in the game.
" Why was that canned? "
" I didnt like it. "
But some of the fans did.
Regardless; ı enjoyed all of them with the exception of rerev's. That game's inventory system is so, so lazy.
