I think you mean if you had played them at their time of release, I played 4 and greatly enjoyed it,
some parts irritated the crap out of me, mainly the useless marines or when you go into a confined area on join operation, yes I mean the missile complex and you run into a good spot and start to kill any one from 900 feet away in the next town over (as yahtzee said something like that in review of Halo wars) and all of a sudden your getting shot in the ass, by ssi griggs, that got pretty irritating, but I just ran faster, then I trapped him in a corner which I filled with grenades, but that went badly, any way, after I finished it I found cod for about 1 pound so I bought it, it was pretty sucky.
then again my granddad did say when they were stuck in the philopenes with the marine, EVERY ONE ducked,
