best arcade games

I was wondering, i want to purchase a few arcade games, i was wondering wich ones are worth it?

I dont want no kiddy games just so u know ;)

I was thinking about:
Shadow complex
alien breed 3
Hydrophobia
Monday night combat
Blacklight tango down (altho i got black ops..?)

Any others i should consider buying?

need advice ;)

Defence Grid: Awakening, Super Meat boy and Castle Crashers are some of the best.

This should go in the recomendation thread, but try Puzzle Quest, The Tomb Raider Game, Duke Nukem 3D, Spolsion Man, Comic Jumper

I'm not sure what you meant with 'kiddy games'.

Anyway, I would recommend Limbo, Super Meat Boy, Trials HD, and Braid.

I don't know if those games would fit as being kiddy or not, especially Braid. If your definition of being 'kiddy' is easy, then those games would do fine. But if you meant kiddy as in colorful and not violent, then I suppose Limbo should be alright.

Toy Soldiers is awesome, try it out.

Super Meat boy, The new PACMAN GAME. They are well worth the money!!!!!!!!!!!!!!!!!!!!!!!
