Brooo same!! Street Fighter 2 was peak nostalgia 😭
Ultra SF2 on Switch 1 is actually not bad though. It has all the classic characters + new ones like Evil Ryu and Violent Ken.

If you want the newer ones like SF6, yeah only on Switch 2 for now sadly.
Have you tried the 30th Anniversary Collection? It has SF2, SF3, Alpha series. Still fun as hell.
