Years ago my parents bought me an anniversary edition of the best selling video game, Myst, along with it's sequel, Riven, third installment, Exile, and the the latest in the franchise, Uru, (yes I know I'm missing 4 and 5).
Only recently have I actually played them. I have finished Myst and Riven and am part way through Exile (I will save Uru for after I've bought 4 (Revelation) and 5 (End of Ages).
One of the most impressive thing about Myst and it's sequels is it's cutting edge, photorealistic (for the time) graphics, some of which I will share with you now (thanks to http://au.ign.com/ for most of these images).
Myst - 1993
Riven - 1997
Exile - 2001
Revelation - 2004
End of Ages - 2005
Uru - 2003
These puzzle solving adventure games are challenging and fun to play with engaging stories that I really enjoyed (and am still enjoying) to unravel.
