Why would someone try to sell you grass? Do you live in an apartment and therefore have no lawn?
Grass!? Why would he try to sell you grass? Are you trying to redo your lawn?
I hate you guys...
Anyway, arcade quality depends 100% on where in the country you are, as well as what specific arcades you visit. Within an hour drive of my house, there are probably a good 6-10 arcades, not including places like Chuck E. Cheese. There are at least three on the beach(es), all of which are pretty much terrible. One of them is significantly better than the other two, but that's not saying much, since the other two are pretty much DDR and air hockey.
BUT, if you go further inland, you can hit up FunWorld.
http://www.funworldnh.com/ Place looks like a castle, and it's HUGE. Three floors of stuff to do. They have games of all ages and types, and the pricing is fair, unlike a lot of places that will charge you a buck to play Area 51 or something. It's a really nice place, they have a cafe in there that is actually surprisingly reasonable in terms of price, serves things like pizza and chicken fingers.
If you go a little further afield (or you live in Boston or Rhode Island or something), then Dave and Buster's is the place to be.
http://www.daveandbusters.com/Food and games and booze, all in one place! Very affordable, half price games every Wednesday, plus they have a "meal deal" where you pay $15.99, get a meal, and a $10 game card which will last you a decent amount of time. Not a bad deal at all. Reminds me that I need to go sometime. One of my friends has a $100 game card that they gave him a few years ago when he slipped and hurt himself there.
So yeah, like I said, it really depends on where you are and what kinds of places you have in the area. Arcades aren't dead by any means, but they are endangered. However, I honestly think that arcades are coming to be back in style. Dave and Buster's is enjoying relatively recent success despite having been around since the 80s. I think that at this point, arcades need to be a "big deal" in order to drive business. It can't just be a little hole in the wall place that you go hang out at on Saturday mornings anymore. Though I do think that strategic positioning of smaller arcades could lead to a successful business venture. The problem is that there are very few arcades that are either accessible or affordable for younger kids, who were previously the main source of income for them.
