Similarly, if MGS2 came with a ported MGS1, it would have had a buttload more pre-orders as well
You already said that and that's what I was replying to.
You were saying that Zelda had a free disk and that helped it get more pre-orders then it would have without the free disc. If MGS2 had that disk it would have gotten more pre-orders.
I was saying that you could also similarly say that MGS2 had a bigger potential user base then Zelda and that helped it get more pre-orders then it would have gotten without that userbase advantage. If Zelda had that potential user base it would have gotten even more pre-orders then it did.
I was basically just saying that, while your correct, there are ifs and buts on both sides.
