I just like the classic, more simplistic feel.
3E-4E is heavily based on miniatures and vast knowledge of rules, and fourth edition just has WAAAY too much sh*t you gotta buy (3 PH, 3 DMG, 3 MM, and suppliments)
plus all oft adult friends played 2E or even 1st when they were younger than me, so it helps me strengthen relationships with teachers at school
besides, it's the one my parents wrapped up, no arguments there
free books always welcomed
