You couldn't be further from the truth on this one. Capcom locked all extra content, some of which was finished on release, behind DLC and sold everyone a bare bones product with Resident Evil 7. You can't honestly compare that to the REQ system, which is honestly one of the most inoffensive loot box systems out there. Calling it pay to win is just laughable when it's mostly cosmetic crap you can earn fairly easily by playing, unlike stupid fight money in Street Fighter V, another money hungry scam from Capcom. Sure, it's preferable if the REQ system wasn't there at all, but can you really blame them when every other popular shooter is doing the same and seeing huge success from it? At least they respected their fans well enough not to abuse it like some other companies.
And sure, you can say "well Capcom is doing the same as everyone else with DLC." However, there's a huge difference between charging people for extra content when the base game is worthy of its retail price, and paying for extra content in a game that was purposely released bare bones. This isn't just something they did with Resident Evil either, just look at Street Fighter V, Dead Rising 4, and Marvel vs Capcom: Infinite. Same exact scam all across the board.
Also, Halo 5 may be the worst in the franchise, but let's not act like the last 4 Resident Evil games haven't received that label from many fans over the years, and for far bigger reasons than they shifted character focus in one game. And let's not pretend like Bungie was perfect either, because before Halo 5, that title belonged to Halo 2.
There is absolutely nothing consistent about Resident Evil... You can't just throw a blanket label over Resident Evil's enemies and say "they're still fighting BOWs" like it means anything. Resident Evil's primary enemies were zombies. That changed with 4 and continued on to 5, and changed again with Revelations and 7. Also, 343 didn't "water down" the covenant. Bungie did a long time ago, and 343 had to pick up the pieces and do what they could to keep the covenant relevant by making them essentially space pirates since the old covenant was already defeated. It's not watering down, it's called story progression.
As for characters... How often do Resident Evil's characters change, disappear for years, or just plain haven't been heard of again? Who the hell cares if they're dead or not, they might as well be at this point. Also, everyone you've mentioned in Halo are nothing more than supporting characters or featured in spin-off games... Not to mention, most were killed off by Bungie. So again, not comparable. As far as main characters go, it's always been Master Chief and Cortana and they're still there.
And why do you mention gameplay and brush it off like it's nothing? When that itself is a huge reason why the Resident Evil franchise is completely inconsistent. Hell, they don't just completely revamp gameplay, they've completely switched genres and butchered their own plot lines in a desperate attempt to move away from the past and make their own one off stories that never lead anywhere because in reality, they're just experiments with the name Resident Evil on it.
This is just completely wrong here. Whether you like the games or not, 343 is passionate about Halo. Most people who work there are developers from other companies who wanted to work on Halo because they're such big fans. They've also done a lot and continue to do a lot for the fans. Every update regarding Halo 6 has been nothing but them hearing the fans and actually listening to them. We hated Locke and wanted more Chief, their response? Chief will be the main character from now on. Fans whined about no split-screen in Halo 5, their response? Every Halo game from now on will have split-screen.
What does Capcom do when the fans hate Resident Evil 4? They say "hey, that sold very well, let's do that again but this time let's make it co-op because online is so popular now." Fans hated Resident Evil 5, what does Capcom do? They further deviate away from the structure and groundwork of previous games because the money is in action, so they go all out on the action and don't even care enough to spend the time polishing the game because they're already salivating at the mouth at the thought of all the money they're going to make. So that backfires and then they completely f*cking lie to their fans about the direction of Resident Evil 7 that they end up releasing a statement backpedaling on what they've stated in the past about the game, by saying that the main series is for experimentation and that the spin-off Revelations series is for the fans... In other words, "screw you guys, we found the perfect way to capitalize on a trend and we're going to tout it as a return to the series' roots despite how much it looks and plays nothing like a game in the franchise because it's not meant for fans."
