Last night I purchased Double Dragon and Double Dragon II (arcade) on PSN. Played both games countless times, but I'll always buy them on whatever platform they appear. Well, except for Double Dragon III, that game totally sucks.
They also had the arcade version of Renegade. I grew up on the NES port, so I only played the arcade once or twice. Last night was the first time I sat down and played all 4 stages, and holy balls, that game is hard. I knew the final boss was a guy with a pistol (same as NES port), but I was not ready for the insta-death Yakuza knife guys in the parking lot. Stage 4 takes so much patience, something I'm terrible with. Still nice to play Double Dragon's predecessor, though.
