for those complaining about the new games costing too much... well you must need some practice cause i can last just as long in an arcade on 10$ now as when i was handed 10$ as a kid in the arcade.
DDR 1$ = 3 or 4 songs, each song is like 2 minutes, you have song select time in between, thats about 8 minutes for a dollar, thats really not bad at all. And this goes for all the music games, beatmania, popn music, guitar freaks, etc.
Big shooting games 1$ = as long as you can stay alive.. i can easily make it halfway through time crisis 3 on 1 credit
Racing games - well unless youre badass at these they are pretty crappy, 1$ for a 2-3 min race and unless you get 1st place youre done after that.
Initial D - although a racing game it gets its own category, "dueling" is the big thing in arcades and when you win a 1on1 race you get to play again. ive had people challenging me for 30 minutes straight i never put in a dollar since i started.
Fighting games - still are all 50c, and if youre any good at all you should be able to beat the computer easily and that takes about 15 min to finish the game sometimes. plus you got people challenging you, etc
like poonga said its about social games now, but its definately not much more expensive granted youre good at what youre playing.. i grew up going to the arcades and i never stopped, so when new games came out i played them got good at them, etc. i think a problem for some of you guys you stopped going after the classics, and now want to go back to the same exact arcade filled with classics, yeah its cool to have a few in the back but really you need new games to keep it going
