I never said they are becoming more complex.
I said (and /or) in context.
Context being, that not many things have changed for most genres over the last years.
And yes, games were always unbalanced, for the most part.
You could cheese many single player games by exploiting a move, a glitch, or an unbalanced feature.
Even darlings like From Soft games are not exempt.
Not that it's that important, Vampire the Masquerade was a buggy mess, it still is one of my favorite games.
And if you want to argue that this is not true for multiplayer games, then I might come to the conclusion, that you either have not played a lot of multiplayer games, or that you did so, but a lot more casually than you would like to admit.
Not that being casual is bad in any way.
As for game developers, "being bereft of talent and creativity today",
Denigrate critique really makes me

Because, it's not really an actual critique now, is it?
Edit.
My fondest multiplayer memories, are from Medal of Honor deathmatch...
A mostly basic first person shooter, in it's most basic form (excluding Doom1-2, I think it was the quake 3 engine?).
Because I loved the pace of that game, and I happened to be good at it, does not mean that first person shooters are not a lot better today, and that multiplayer is not a lot more interesting.
