It can run those titles if devs put the time in to port them. It won't look as good but you can make up for it in other ways. Nintendo has ported multiple titles, very well I might add, from console to 3DS. So, don't believe that nonsense about Switch not being able to run x game. It's just that devs would rather not put in the effort if they're not sure there will be a significant return, which is not a guarantee at this point but if that super low effort port of SF II can sell nearly a half mil, imagine what a AAA title would do?
