There is nothing wrong with arcade styled games if they're executed well, it's just certain elements of arcade styled games end up feeling half-assed on consoles. While I don't own the Metal Slug Anthology, I've read that game gives gamers the option of play the game with unlimited continues or limited continues. Judging from one time I played Metal Slug 4 at an arcade, I imagine every game on that collection is probably piss easy with unlimited continues turned on. Granted, the continues setup worked well for the arcade version because it was a good way to get people to continue putting in quarters, but it feels illogical in a home console setup. A time limit also made sense for the arcade version of Sonic games because you don't want some kid hogging the arcade machine for six hours to explore every ounce of every level. It doesn't make sense in a home console experience because it feels like an unnecessary add-on from the arcades.
