How long does it take to complete the entire game?

Depends on if you try to find everything and if you're interested in achievements.
And of course also on personal skills.

If you just want to finish them in a normal way, I would say something about 60 till 80 hours could be possible?
There are many levels where it's not unrealistic to play 1 hour.

And there are bonus levels as well.

Cheers!

Each game is roughly 10-15 hours long on a first, casual run. TR3 may take longer, TR1 may take shorter, due to difficulty & level design type disparities between titles.

The first two games are a lot more straightforward overall, and TR1 doesn't have unfair obstacles besides a few enemy types that only appear in the final levels (and they're still arguably more bearable than regular gun enemies from TR2).

TR3 is sprawling and easily confusing and frustrating for a first time player, filled with a lot of sudden "do-or-die" traps with little leeway. It required me replaying it a second time to actually start to like it overall.

The extensions are more like 4-6 hours each, and they count separately to the first values I gave. They generally assume you've played their main game counterpart before, especially TR1 Unfinished Business, which immediately starts out brutal.

15 hours is the average for TR1, but because its your first try playing, maybe 20 or more. Then the other two also average higher.

If you know what you are doing and is good at it?
5 to 10 hours.
If you dont then there are some 54 levels so between 1h to 90min per level you would take between 54h to 81h IF you dont explore more, dont die often and dont get stuck in any level.
