I'm sure many of us crossed paths. I too was in Kevin Street in the early 90s, and spent most Saturday mornings at the arcade in the Sports Bowl, money or no money. Quasar used to have a league there too weekend mornings which was great craic.
When Leisure plex in coolock first opened it was great, downstairs eventually had some great early 3d games like ridge racer and Virtual Racing and virtual fighter, up stairs had R-Type 2, Tumblepop, Street Fighter 2, Konami X-men, crackdown, A Neo Geo multi system with FATAL FURY, Bowling, a Baseball game and Robo Army.
Barneys in Dublin was a bit grubby but it was where I first played Street Fighter 2 and Mutant Fighter which was a terrible game but it had fantastic graphics and sound design.
I went to Dundrum Bowl to play Q-Zar and their Aliens cab a couple of times.
But otherwise it was the arcade on O'Connell St, down where Marathon Sports was/is, Dr Quirkies probably came a little later.
I used to love Stunrunner and Temple of Doom there.
