All metal slug in a cake, not too expensive (if you find a used version of) it's worth it. Initially these games were released on Neo Geo and costs 150 to 250 euros each (yes we really took the players for pigeons). Since each title lasts an hour at most, only a compilation is really interesting. The box version is less expensive than downloading all titles on WiiWare. Let's talk about the game now. it's fun and nag but I can not help but wince before a very heavy appearance: even a god of the pad (or wiimote here) loses tons of life in this game, so you might not have feel really win but to lose by continuing to move forward ... yes the purpose of the original games (coming from the arcade) were you let go more than 5-franc pieces into the terminal .. . and you can not help but make a good thirty continuous (three lives each) to finish one metal slug ... so we look with shame his score at the end but the pleasure is there and it is the principal.
in brief: metal slug is fun, lively and nag BUT above all, it is one of the most famous and most popular games of its time. Today it fits perfectly in the "pearl of retrogaming" that amateurs can not ignore.
