Okay, firstly, inb4 this gets moved to General Gaming.

Secondly, whilst I agree that there are older games that haven't aged well, there are also plenty of older games that are just as brilliant now as they were back then. As an example: ...wait for it... SMAC. The game came out in 1999, it looks like freaking this:

(SPOILER)

...and it is the greatest video game I've ever played. This is not nostalgia speaking. Why? Because I never actually sat down and played it until about three months ago.

The same goes for X-Com: UFO Defense:

(SPOILER)

...which came out in 1994, and proceeded to thoroughly engage and enthrall me for the very first time in 2010 or 2011 or whenever I first started playing it. (Hint: it was recent.)

Thirdly, it's all pretty subjective. A lot of people say that Ocarina of Time (for example) hasn't held up well, but I played it again about two years ago and loved it just as much as always.

Fourthly, we all know when Pike shows up in a thread because we promptly start talking about SMAC and X-Com.
