Marvel Super Heroes vs Street Fighter, King of Fighters 97, Layer Section, Virtua Fighter 2, Street Fighter Zero 2(3 if you can afford it).....there's so many, it all depends on your taste. Mine is obviously fighters, and there is a wealth of fighters and shooters on the Saturn. These listed can be had reasonably. Great RPG's can be had for little if you have Japanese skills. You seem to be from the UK judging from the currency you use, so I would recommend heading over to www.videogameimports.com because they are priced well and are located in the UK, so shipping won't be bad.
Cheers dude, aye im from the UK, used videogameimports.com a few times actually and they provide a good service. I'm also a big beat em up and shoot em up fan, love RPG's too so i suppose i should be looking out for those titles mentioned. Any other people have recommendations?
