If you don't like the combat in the game, then I don't blame you for lot liking the final parts of the game. Nor does it take away stealth as an option. It also doesn't have a section where having a ranged build over a melee build, or vice versa puts you at a disadvantage. Yes it does have a larger combat focus, but at that point, you should have something like firearms or melee/unarmed at a high level, while still having a high social stat for everything beforehand.
A common opinion is that the game takes a large drop in quality by the end, but I don't agree with that. It's too bad how buggy and unfinished it was at release, but that was nearly 10 years ago, and has since been fixed and polished up. Each with their own set of skills that are very satisfying to use.
Different builds to make, different choices.
The atmosphere, the lore, the characters, the dialogue, just amazing.
