The quirkiest of the bunch.
Legend gets a bit of flak, as it is the largest departure from the originals. It tried to make an exploration/puzzle/platformer into an action/platformer, with a lot of Bond/Bourne levels and at the same time 'dumbed it down'. People criticised it for sections with no exploration and just shooting, motorcycle chases reminiscent more of mobile games, fully linear platforming, lack of inventory/object puzzles, and, most of all, quick time events, which sealed the 'dumbing down' argument. Most of it boils down to 'not the Lara Croft we loved' and is now largely irrelevant, with this game becoming a classic itself.
The action sequences are rather simple and you will spend considerably less time on shooting than on puzzles and platorming, but what they lack in gameplay, they make up for in coolness - how often do you get to jump on a motorcycle over a train while shooting? Platforming also requires less skill and thinking than before, becoming just a more interesting way of moving around while solving puzzles, which are just about right for not strictly a puzzle game. So while everying is easier, it's not without challenge, and you proceed much more smoothly than in a precision platformer or a point-and-click. The game is entertaining in the way watching an Indiana Jones film is: hopping from one location to another, seeing and doing outlandish things, without any frustration.
The level variety is second to none, and they ooze atmosphere; temples and tombs look and feel the part, rather than being thinly disguised platfforms. I recollect single levels from other games, but I can recite in one breath all the levels and sections from Legend. QTEs are few and far inbetween, and it's only the duo of advisors you have on the line that can get annoying,
While it does feel dated, it's still 100% worth playing, simply because - outside Uncharted - there is nothing quite like it. Just approach it with expectations for something relaxing, rather than particularly challenging.
