Definitely (1 mostly.) I love the classics!
Let me tell you why.
First, most console games are just to easy. Arcade games, on the other hand, are a true challenge because they want to kill you fast so you will dump another quarter in.
Second, I want to relive my wasted youth. I still play them at the local pizza joint. My son and I waste ten bucks a week on ms. PAC MAN, Defender, and Galaga.
Third, the simplicity of games like PAC man, tempest and such are great for playing while drinking. Also, the controls of an arcade game are easier to use when you are buzzed.
Finally, yea I guess it is a little about showing off. Having an arcade cab with all the classics will be somewhat of a status symbol in the circles I run in.
