I just ordered two of the manliest PC-Engine games, Double Dragon II and Ai Cho Aniki. Even though I am primarily a TG16 guy, I am excited to add these games to my list of 20 or so PC-E games. Double Dragon II on NES is one of my favorite games on the system, and the PCE appears to have the definitive version.
...however, I also thought I was getting the best version of a game when I ordered PC-E Ninja Gaiden, and that was not as good as the NES.
