You've just stated one of the great paradoxes of our day my friend.

Halo is doing something that most other games right now ARE NOT. It's been doing it for 10 years and, right now, it's different from the mass of gritty, "realistic", twitch based shooters. So this becomes a rather interesting conundrum: which is actually "outdated"...the same standard that every other game on the market adheres to right this very instant...or the one game that does things differently?

When everything's the same, you get disasters like the sales of Spec Ops: The line. Great game with one of the rawest, most fascinating stories every conceived for a game, backed by fantastic characters...which did not achieve success because it ticked all the right boxes expected of a AAA release.  Yeah...they really needed to freaking evolve.

Just like Resident Evil 6 of course. Get it in line with every other 3rd person shooter out there, gut it of most of what made the series great at one point, and release it out into the wild. Gamers were indeed VERY pleased with that one...weren't they?

Yes...

Yeah. I was too lazy to read past the first page before I made that comment...

Same here, please accept my sincere apologies OP, you got me...
