Ahh, yes. The much-anticipated "You only wanted Civ 4.5" argument. I was wondering when it would rear its ugly - and I do mean UGLY - head.
So the flip side of that coin is "the only people happy with Civ 5 are those that hated Civ 4." We know such an absurd remark is ridiculous,
Detour for logic review:This is a bit of a logical fallacy. If I say that PC gamers are the only people who can hate consoles. It doesn't imply that the only people who can love consoles are those who hate PCs. There's no logical connection. You can argue one or the other statement without having one imply the other.
Statement: If A, then B
Converse: If B, then A
Inverse: If not A, then not B
Contrapositive: If not B, then not A
The only thing that holds by logical form is that if the statement is true, then its contrapositive must be true (or both must be false). No guarantees about converse or inverse. One more spin: Note that the inverse is the contrapositive of the converse

So if we take the statement "If you hate (dislike, criticize) Civ 5, then you wanted Civ 4.5", then the contrapositive would be "If you didn't want Civ 4.5, then you don't hate (dislike, criticize) Civ 5". Note that both statements are proven false by one instance of a person who did not want Civ 4.5 but still has issues with Civ 5.
POM's example restates as (first statement) "Every console hater is a PC gamer", or "If you hate consoles, then you must be a PC gamer."
Second statement: "All console lovers are PC haters", or "If you don't hate consoles, then you must not be a PC gamer.
The second statement is the inverse, of the first, and it certainly does not follow that if the first is true, then the inverse must be true.
So is SuperJay's "flip side" statement the inverse, or the contrapositive, of the notion that "If you hate (dislike, criticize) Civ 5, then you wanted Civ 4.5"?
"the only people happy with Civ 5 are those that hated Civ 4." (SuperJay's flip side) is equivalent to which of the following:
"If you didn't want Civ 4.5 (or don't like civ 4), then you don't hate (dislike, criticize) Civ 5" (contrapositive), or
"If you like Civ 5, then you hate Civ 4" (inverse)? It is this one, since if the only people happy with civ 5 are the civ 4 haters, then hating civ 4 is necessary for liking civ 5, and thus hating civ 4 follows from liking civ 5.
Back to main road ...
