I thought that I should add my 10 cents. (And yes, you may have seen it in a different thread )
"Adding my 10 cents again, I think that games from all eras are good. Harlem Globetrotters (1978, Bally) is one of my favourites.
But, I still respect all of the games made today. I think that the way the rule sets have developed has allowed for more intriguing games where you can take way longer to try and process how the game works and how to get to a top score (oooh Top Score is a good game too )! The art has changed because obviously technology has changed too. I think that some of the modern art is way better than the older games, e.g. I do actually think that Ghostbusters has one of the best art packages ever - however looking at the older games has its value. I love Bally's Firecracker. Especially the cabinet. That kind of art, although it looks weird and not realistic and cartoonish, is SO COOL. Look at the moustache on the cabinet. You don't get that with modern machines."
So I like everything. I change my opinion all the time on what my absolute favourite is, but for the moment I'm definitely enjoying playing some old SS games and EMs.
