If they were to remaster Gears of War 3 they need to leave all of the movement and weapon tunings as-is. Modifying any of these opens Pandora’s box and would ultimately create an abomination. They don’t know how to tune a game in a meaningful and effective manner so don’t touch what’s not broken.
I could see the argument for a fire-rate cap on the Hammerburst since you’d be introducing that mechanism to PC or Xbox players using KBM. If they were to put any regulation on that I would hope that it is so high that you really can’t pull it off with a controller. Though once again, I reiterate my point above that it is a slippery slope.
The only changes they should make are additional cosmetics and such. Bring in some of the newer characters and a couple of the Gears of War 4 or Gears 5 maps (that weren’t complete trash). They could charge for all these additional skins as a way to keep revenue coming in and I’d be fine with that.
This would allow them to focus solely and pumping out maybe a couple of maps and a ton of character skins while not having to balance the the game. I’ve said before with all the turnover they’ve had and the failures that Gears 5 has endured they need to prove themselves once more. What better way to get back to the drawing board than to recreate the majesty that Gears of War 3?
