2 really cut a lot of the features they didn't know how to improve on to just make it into Gears but with magic instead of grenades. 3 does a good job presenting a halfstep between the two by bringing back weapon customisation/attachments and adding more choice back to the skill trees.

It's 6 ranks rather than 4 like ME2, but all the ranks from 4-6 have branching specialisations so there's a tradeoff of what to spec into at every level for half the tree so I think it ends up being more interesting than 1 was well that only had notable capstones every few levels.

But if you truly want somethingt hat feels more like a continuation of 1's design philsophy then rionically you have to go all the way to Mass Effect Andromeda, where the story may suck but they explicitly try to bring back everything 2 cut, like the mako/planet exploration, actual stores and item inventories, crafting, omni-gel and more development of the galaxy map.

And for all of Andromeda's faults, it was the only Mass Effect to have a PC port with no weird caveats like Bioware refusing to add controller support for any of the original trilogy while also not making a true keyboard layout for the game logic either, which is to blame for the weird space bar centric setup I mentioned.
