One of the “first games”?

What on earth do you mean?

One of the first games released on the N64 system.

From context he likely means the first games for the platform.

I vaguely remember it was a launch title.

Some people need everything explained don't they? "What do you mean first game? I distinctly remember playing tag at school and that preceded Wave Race 64 by at least 2 years. Please stop spreading FUD".

Perhaps but it is easy to forget that sometimes they simply either don't understand or that English may not be their primary language.

I try to assume that such things are genuine questions unless facetiousness is obvious.

Makes for a more pleasant place that way.

It's crazy how ambitious it was to have Mario 64 as a launch title, particularly when you compare it with the other launch title, Pilotwings 64.
