Thus,
although the
similarity among strains means that growers can crossbreed them easily, it also means that the collected strains do not contain enough variation to provide
much natural resilience to pests and disease; if one strain is genetically susceptible, chances are good they all will succumb.
Although Resident Evil 4 (which I have just now added a comment for) and Metroid Prime share some
similarities in fierce encounters with enemies, Metroid Prime is
much the better game (in fact I rate the Resient Evil remake above RE4).
