There are two cool places in both Ekkamai and Phrom Pong (same franchise, Gamer Guild or something along that) that does 2 hours unlimited gaming + drinks (also have non-alcoholic ones)
They are stocked in both modern and retro consoles (w/ some japan exclusive cartridges), and it's a great place to meet other gamers, like a crowd playing Fifa, a korean on tekken and a wholesome mom and her kid playing Split Fiction
