This is where I'm at too. I could more or less have the same experience with the original releases and a few mod packs.
It just wasn't enough for me to justify a purchase. Granted, if I was a new player and was interested in the series, it's a tremendous package, but seeing as I'm not, it's just not enough for me.
As I hadn't played any of the DLC (nor own any system to play my 360 discs anymore), this was an obvious buy. And fairly good value for money still for someone in my situation, you get a ton of content to play (some of it completely new), even if it is an older game.
But as far as remasters go, while this isn't just a resolution and/or framerate bump, I think it's still a rather low-level attempt. For example, there are improved textures. Apparently AI upscaled from original assets, then tweaked by artists afterwards if needed. Nothing wrong with that, but it's not like they were done from scratch Bluepoint style (and at least on PS5, there still is the occasional "eww" texture here and there despite the facelift). But while the resolution and textures have had an upgrade, as far as I can tell no such thing was done to the 3D models of the characters. The faces, ehh, they're fine enough; rather unnatural in some scenes and there seems to be a galaxy-wide infection of crazy eyes going on, but that's to be expected from an older game and especially one with tons of dialogue and different story paths so most of the conversations will not be mocapped. It's the gear you have and clothing/armor in particular. While this does improve somewhat across the trilogy, especially in the first game most people look like they're wearing wetsuits. If there are any substantial changes, I'm not seeing them. Making comparisons to Bluepoint may be unfair, but take something like Nathan Drake Collection. It was a remaster, not a remake, but despite that they for example changed a rope in a cutscene, it got new geometry and a position that makes physically sense. Or an archway in another cutscene, instead of angular PS3-era style make it nice and round. In both cases we're talking about a cutscene, so not really essential stuff (of course there are so many in-game improvements as well), but the (Blue?)point is that in both the new and improved asset is visible for like a few seconds in an entire game. Yet it was something that was done, and I think it speaks for the amount of effort that went into the collection. I'm not seeing nearly the same level of effort on display here; it's not just a different ballpark, it's completely different league.
Perhaps BioWare didn't have enough resources to put into this project, or EA didn't give them enough budget, or Covid, or or or. There can be several reasons why we got this kind of a remaster, but I reckon that's all we're getting, no need for a change.org petition. Still, at the very least one would expect your settings would carry over from game to game, this is meant to be played through entirely right? For me that would be invert Y (yes, I'm one of "them"), subtitles on and slight adjustments to audio mixing. Does it take a long time to do those changes? No. Should I need to do so for every game? Also no, a reasonable assumption would be that they're copied from the previous game with ability to adjust them if needed. But no such thing here. No attempt to "integrate" the games (like a single main menu instead of a launcher for each) either. Anecdotally, I started playing ME2 really late after already long gaming session and getting to the end of 1, so I was only half-awake and annoyed that I had to modify the settings. Few taps on the controller later, back to game for a while, then the sensible move of going to sleep. Next day really giving it a go, and pretty soon I was thinking to myself "it's been a while so I don't remember everything, but HOLY FUCK these checkpoints are so much more brutal than I recall". It took me some 10 hours of playing to get the idea of checking out the settings - and lo and behold, there's an option for autosave which I had accidentally disabled. Yes, I'm an idiot and it was my fault (I blame sleep deprivation, late night whisky shots may have also played a part), but it wouldn't have happened if I didn't need to go into the settings, which I really shouldn't have needed to.
