I did see it at the Apple Store to Jenny. I'm sure sooner or later they will be available for the newer apple computers. There are 2 TR games listed.
Yes there are Tomb Raider II ($7.99) and Tomb Raider Underworld ($19.99) at the App Store.
Tomb Raider II for OSX 10.6.6 or later.
Tomb Raider Underworld for OSX 10.6.8 or later.
But Underworld isn't one of the old series.
I'm guessing they'll have Tomb Raider III through V before they have Tomb Raider I, since TRII through V are Windows-based and TRI is DOS-based. TRII through V could probably use the same wrapper, but TRI would probably need a different type of wrapper.
