I've recently been replaying Chronicles on the PS1 (which is FAR more polished than the PC version, btw), and I really do think it's a great little game. Sure, it's a tad short, and it may have been produced purely as filler between TRL and AoD, but it's got some really unique settings and gameplay, and I just love the focus on narrative and cinematics. It really helped flesh out Lara's character and establish her as the tough, snarky badass we came to love.
Plus getting a sneak-peek of AoD as a reward for finding all the secrets was a real treat for my ten year-old self
