It may be the end of an era, but the legacy lives on. Some of the finest arcade fighting, platform, and shooting games ever to come out. The library is big enough that any one can easily play for a lifetime and enjoy the games.
The fact is that it looked very much like SNK would permanently close back in 99/2000, but very fortunately for us it was resurrected and games continued to come out for another 4+ years. I consider that we were very lucky to have that last run of games, some of which are very good to excellent. When this "era" ends, yes it will be sad, but the library of games that came out are fantastic in total and the system has a lifetime of gameplay in it, IMO.
