Was too curious about Tomb Raider 3 so gave it a go straight away... and noped out on level 3.
First the things I liked: visually it looks better than the previous games, lighting has been greatly improved. Colors can be quite vibrant, so things like torches and stuff are much moodier. Audio has also been improved, sounds are crispier. As for enemies at least the first two levels were like in TR1, only animals with much better pacing than in TR2, but I remember there being plenty of humans on later levels so it could stoop back to TR2 style. Didn't bode well when I found a bazooka round...
But there's two reason why I quit. First something I didn't mention while writing about TR2, the amount of traps was far greater than in TR1. This wasn't too terrible since even the PS1 version had free saving this time, but on my playthrough DuckStation emulator clocked 25h total playtime while the game itself clocked 17h. Meaning there was 8 hours worth of reloads and retries. Not all of that was because of traps of course, reloading a save on the PS1 version alone takes a moment, but it did have more trial and error than I cared for.
The second level of TR3 already was full of traps. Many of them the kind that have a good chance of killing you on your first time unless you get lucky. To make it even better the PS1 version kinda still has free saving, but this time each save costs a save crystal, which are something you need to find and collect in the levels and there's not that many of them around. Which is to say the amount of trial and error goes through the roof, and I already got my fill of that during TR2.
Then there's the second thing, while the lighting has been improved the darkness it creates gets annoying. Items are harder to notice and you constantly have to use flares to check you don't miss anything. And those flares last pitifully short time. Even when it's not dark items on the ground are harder to notice than in the previous two, right on the first level I ran straight past an important key without noticing it. Stuff on the ground just doesn't pop out as clearly as before, I would have had to increase brightness on my TV if I would have continued.
Also the framerate of the PS1 version isn't great, improved lighting clearly took a toll. In the end I can see why I completed this one only once back in the day. But I'm not ready to call it a bad game, the PS1 version just isn't ideal. The PC version still has those save crystals but apparently they got changed to healing items, saving is free and can still be done at any time. I don't have the PC version but if I ever end up with one I think I'll give that a try.
