1nsane 2.
So many good memories of dragging my desktop PC, CRT monitor, desktop speakers, and LAN hub over to my friend's house. Pizza, white castle, smoking schwag and playing hours of king of the hill. 1nsane was just the shit to get your friends worked up. Rune was cool, UT was most excellent, but 1nsane was something special.
For so many years we yearned for a next gen copy. Then we got 1nsane 2, and what. the. fuck.
