you could also make some nice looking 3x5 cards that list all the indie games available in the arcade!
that way people can check out the games at home afterwards

playing in an arcade or playing at home is completely different.
the added social component + the atmosphere + hi score competitions etc sets it apart.
if your upcoming arcade would be in my area i would visit it and pay to play the games there (even though i have already played them all you know)
and well of course people want to know the names of the games.
give them what they want.
this makes the whole thing also more shareable you know.
visitors can tell their friends more easily what kind of games they have played there.
instead of "eehhhm.... dont know what to say cause i forgot "
now imagine the same scenario when one guy has all the names of the games on the little 3x5 card (with added tiny screenshots and short description)
it might go like this:
guy: "oh well you know... theres this fast paced arcade platform shooter called super crate box blabla...check out these delicious graphics!
oh and theres also this game called blabla etc..."
friend: "...lets see. spelunky...great! i know that game. haha great idea to play it in an actual arcade cabinet. dont know the other games.
well i have to visit that place for sure!"
moreover:
consider to speak to indie devs who have released commercial games and ask them if it would be possible to have their creations in the arcade as well.
for example bullet candy perfect, irkukandji, scoregasm (
charlies games) and ultratron, droid assault, titan attacks (
puppy games) would be great additions i think.
