Building a Makeshift Arcade at a Music & Arts Festival - Need Some Game Suggestions!

For the past 5 years, I've been running an independent music & arts festival in my hometown. This year, we've decided to introduce gaming into the event, with the hopes of building a dynamic arcade featuring nostalgic/classic titles which festival-goers can play and enjoy freely.

My questions to you is this: if you were to be tasked with building your own arcade, which games would you most definitely include? No wrong answers!

Definitely umk3 and nba Jam. Would help make you some money 😃

Mortal Kombat or Street Fighter would also be great choices, they are dynamic, classic and multiplayer which bolsters competition and interest
