I recommend this for your collection and cheaper than collecting real AES or MVS NEO GEO carts lol. Samurai Shodown Anthology (PlayStation 2) This is a great SNK fighting game. SS1 was the beginning to great success SS2 is the top tier of the game, SS3 is good lacks something I can't put my finger on but it's fun, SS4 is my favorite next to SS2, SS5 is boring to me and SS6 is very good!!! In SS4 you can kill your opponents and cut them in half, that was taken from SS3. I owned the original SS5 cart for my MVS system and to me it was boring so I sold it and the Anthology remake of 5 Special and calling it SS6 is GREAT! Originally SS5 Special was only released in a very small amount in Japan back when the MVS NEO GEO was still in the arcade and now a days goes for at least $500 for just the cart without the kit.
I suspect PLAYMORE reworked SS5 Special to create SS6. SNK took everything from SS2&3 that were good and combined it to make SS4. Out of the 6 games in the Anthology SS2, SS4 and SS6 are my favorite. Ultimate is, by having a complete fighting roster where everyone ever was playable. Very good deal! Great games in the bunch. Samurai Shodown VI (PS2) / Samurai Shodown Anthology (Wii) was what Super Smash Bros.
