"In the co-op, both players will play as Chuck Greene"
lazy devs.
It depends on how deeply integrated they choose to make it. Yeah, each player is using Chuck Greene, but each of them gets to use whatever clothes and accessories they've unlocked, so it's not like two identical characters are running around on the screen
(cough Earth Defense Force /cough).
You might say, "Why not change up the facial features at least?" but even that invites a host of issues with no tangible returns on the effort. And where do you stop? Don't you also need a different voice for the character, since he's not the same? And how about a different angle on the story...?
Speaking of cutscenes, which the article says use the player model specific to the local player, what if they specifically refer to "Chuck," or "Greene," or "that dirty blonde haired guy," or his daughter, or some other bit of specific information? Should the development team have prepared separate assets for the co-op experience so the Player 2 could feel more immersed in being someone else's sidekick? And then have QA devote the extra time to confirming that the game's co-op specific cases work separately from the main player's?
This method is by the way,
the same as used by Saints Row 2, which is largely revered on this board. Nobody bitched about it there.
Anyhow, yeah "lazy" devs. :smh
