ok cool, i'll stick with it. I do like that there isnt loads of keys, sometimes it seems like games use way too many keys for interacting with things, when you only really need one.Different weapon types do affect enemies differently. Half the 'fun' is the weapons and finding the particular one(s) that suit your play style, but yeah there. are. so. many...
I'll do some reading online, perhaps i can find a weapons guide that will help me get started
