## What it is
OpenLara is an open-source reimplementation of the classic Tomb Raider game engine, supporting original game assets in .PHD, .PSX, .TR2, and .TR4 formats. It runs as a standalone application on desktop platforms and in the browser via WebGL.

## Use cases
- play classic Tomb Raider on modern systems
- run Tomb Raider in a web browser
- play TR1-TR3 with enhanced graphics like caustics and widescreen
- open-source replacement for the original Tomb Raider executable
- play Tomb Raider levels from PSX and PC versions

## When to choose
- you own classic Tomb Raider games and want to play them on modern hardware
- you want enhanced rendering features not in the original engine
- you want to play Tomb Raider without installing the original game

## When to avoid
- you want to play modern Tomb Raider titles (2013 reboot series or Angel of Darkness)
- you need full bug-for-bug compatibility with the original engine
- you want a level editor rather than a runtime engine
