It kept the dark color scheme for a while but got less grainy with two and had some okay variety, 3 was much better about lighting and had some cool level variety. Core gameplay is always the same but they add new weapons and small features to mix things up. I think there's a good chance you'll like 2 and 3, I didn't much care for 1 either.

2 and 3 are good games( I would say 3 is great) but Judgement is abysmal and 4+5 are continuing the story for some reason when 3 was supposed to be a definitive end. Gears 4 also somehow regressed in the weapon category consisting almost exclusively of weapons from the first game and weirdly edited versions of guns from other entries.

Not dissing you but I've never saw anything really wrong with the gameplay barring control clunkiness, I wish more games had gunfights that didn't end in 20 seconds or less.
