I think the reboot is pretty good in terms of pure entertainment, with stellar graphics, cool set pieces and satisfying, albeit dumbed down, gameplay. But anyway you see it, these new games are a far cry from what the series initially pioneered and I would love a return to that. The level design and exploration in the OG Tomb Raiders are nowhere to be found in these modern games which makes them lose the staying power of the originals.
Unfortunately I think a return to roots won't happen, since sales declined very heavily even after Tomb Raider 3, with the formula quickly becoming stale, prompting the first reboot. Granted it was a different time then, but I'm hesitant SE and Crystal wants to revisit old and proved territory in favor of these new state of the art-games they keep churning out. On the other hand, the formula for these games are also beginning to wear thin, so maybe a third reboot would force the series back to its roots. It would also be nice if Crystal could forge its own identity for TR instead of wanting to be Uncharted (which is ironic since Uncharted pulled a lot of inspiration from Tomb Raider).
