No, I think "decent" is the word I wanted, and of course it is a subjective opinion.
For comparison, a game that is not particularly AAA (certainly not by today's standards) would be something like Civ 2; this is another decent game that has huge replay value. If WoG had replay value similar to it, then I would have really gotten my money's worth, from my perspective.
But then you go on to make a rather odd argument, which seems to me to be moral in nature, suggesting that I should feel bad because I like getting lots of stuff for very little cost. Well I'm sorry, I don't see it that way; the key advantage of software in a global economy is that marginal cost is tiny, so excellent content should be cheap.
And the experiences I've gotten out of games like Far Cry, Thief, Civ 2, etc., have been infinitely more memorable than the gameplay I've had from WoG.
Thief: once, when looting a room, I was surprised to hear a guard say "what's going on here then", and I was just able to avoid detection by nipping into the shadow behind a pillar. When I was playing it, it affected me so deeply I walked down the street differently after sundown.
Far Cry: the experience of coming out of the cave where you wake up, and into the lush Pacific island environment, was amazing; one of the first things I did after I got my hands on my first jeep was drive through at relatively high speed past most of the mercs on that first level, all the way to cliff looking towards the aircraft carrier, and jumping out at the last moment, and watching my jeep sail over, crash and explode at the bottom. It was cinematic, unscripted, and I was in control.
Civ 2: Well, every time I get into that game, and I can still get into it now over a decade later, I build a country that becomes part of me, the names and locations of the cities familiar. It becomes my own territory, a place I feel at home.
WoG: it's a puzzle game, it's a bit like those ad-sponsored flash timewasters, only drawn out and developed a bit more. But I just don't see it as being particularly valuable. Sorry for feeling happy about having that judgement.
