OpenLara VS TR2Main

I didn't notice anything suspicious in his explanation of how the AI works, though he glosses over navigation. I assume he is using the OpenLara engine, in which case he easily has access to level geometry or other parts of the game at runtime that would normally be inaccessible. However when watching the AI play, I got the impression there was two much overlap between what the AI does and says. For example, based upon what I understand of the explanation of how the AI works, the part playing and the part talking are not interacting with each-other. Voice lines are simply generated based upon what is on screen and there is no true common intent behind the AI's actions and speech. This makes me suspect the entire video is simply a scripted imitation of AI.

You can try source engine ports like xash3d diii4a Serious Sam Freedoom OpenLara Quad Touch and Source Engine

It is, it’s the OpenLara engine, so it’s running native code rather than emulating the PSX version.

OpenLara

You can play it online here, the github link on the page also has a downloadable version that plays offline and works with the controller. http://xproger.info/projects/OpenLara/

Tomb Raider II / The Golden Mask - TR2Main https://github.com/Arsunt/TR2Main/releases

TR2Main. There's a folder called "Extra Options" that'll be in the install folder when you're done. They can add things like the animated item screen and PSX status bars. You can use the PC or PSX FOV.

If you plan to play TR2, go grab the TR2Main fan patch for it, makes it run nice and smooth with controller support if you want it. TR3 is the probably most annoying to make work, due to some bugs with keybinding and alpha blending. TR4 is a little better thanks to Tomb4Project, same with TR5 (Chronicles) and Tomb5. I couldn't get controllers to work with 3-5 so i just got used to keyboard controls. Speaking of keyboard controls, with 3-5 i've been rebinding sprint to num0, sprint to num1, duck to num2 and flares to num3, so you don't have to really take your fingers off the arrow keys.

I've been playing through the original ones, you can use community updates like Tomb1Main and TR2Main for controller support on PC. I played 1 and 2 using a wireless xbox one controller on PC, which was really nice.

Tr2Main fully supports gamepads natively.

For Tomb Raider II, there's a fan patch called Tomb 2 Main that also adds native support for modern versions of Windows, widescreen resolutions and the ability to activate some features from the PS1 version that are absent from the PC version.
