Call of Duty: Modern Warfare is just Warzone. Not sure why they switched the covers. I'll not entertain the suggestion that an arena shooter has a longer gameplay loop than a BR.
Rainbow Six Siege has a more robust loop. Choosing different operators, setting defenses up, encouraging communication + coordination between teammates, offense vs defense, utilizing gadgets + weapons during action, dying, watching teammates perspective...That's like a ~5 minute loop where the player is making unique choices during phases that all feel somewhat different.
Halo Infinite is literally...randomly spawn on map, run towards action for 7 seconds (arena) or 15 seconds (BTB), hope there's a weapon spawn along your path, grenade/shoot/melee for ~20 seconds, die, wait for 10 second respawn. The loop is short, repetitive, and 40% of your time is mindless (running to action + respawning). The game produces almost zero meaningful watercooler moments because it's based on design that didn't understand the mediums potential. There's no drama in slayer, control, CTF, or powerseed modes. Nine times out of ten the match suddenly ends and you're left thinking "Oh I didn't know we were nearing the end there." It's dull design.
All the games you listed have short loops. I'll agree.
Vanguard is struggling BECAUSE of it's short loop.
Black Ops Cold War came out 15 months ago.
Rocket League came out 7 years ago.
So congratulations Halo Infinite, you released 3 months ago and you're doing better than 3 hamstrung titles. *Kazoo sound*
When you say broken are you referring to BTB, which was literally broken for a time, or are you talking about foo foo cosmetic progression systems?
Go look at the multiplayer TITANS that came out over the last decade or so...
PUBG
Fortnite
Rocket League
Minecraft
You're talking about foo foo progression and these 4 Chads had literally none to start. Broken > None. All 4 experienced massive growth curves because NEWSFLASH gameplay is what matters. What kind of gamer am I talking to?! You're referring to skins and emotes as "major systems"? I'm sorry, but gameplay has always, and will always, be king. There are no "major systems" located outside of gameplay. Only frosting and glitter are located outside of gameplay bro.
I'll say it very simply...
What entertained the market in 2004, is not capable of entertaining the market today. The industry has matured. Games have progressed. The public is more sophisticated today.
Eh, I found a post of mine asking about new content coming with the Dec 8th release. Asked it on Nov 15th. I recieved a clear answer and no one debated it. It seemed understood that the community knew at that point. Then I had to gag on all the praise everyone was giving multiplayer over the next ~4 or so weeks. I've never gagged on so much praise in my life.
This is very Shooter McGavin, and I love me some Shooter McGavin.
