Hnnng, provided this meant no microtransactions at all I couldn't have been a happier camper. The veritable torrent of cosmetics and the arcane market it spawned is in large part what drove me away from team fortress 2 after all. But... there's no way they're going to stop at a single skin for six out of the 21 characters, is there? It is worth noting however that, barring some exceptions in world of warcraft, blizzard has yet to employ the full on buy-in + microtransactions double dip. (As far as I know anyway, do correct me if I'm wrong.) Instead they seem to be looking for alternatives, like diablo's real money auction house or WoW's game time tokens. So I do have some hope they'll make a point of everything past the initial purchase being in-game unlocks. No doubt some of which through their other games, which is an alternative to microtransactions in and of itself. Hmmmm, we'll see. As someone who was hoping for it to simply be a one-time purchase instead of another microtransation platform, this is heading in the right direction. But we're not past the off-ramp into microtransachistan yet...
As for asking full price for a multiplayer-only title, I do not mind at all. Products are worth what the customer is willing to pay for them. What I saw from the beta is worth 40$ to me. (Provided it turns out that's the only money they'll ever ask for.) Simple as that. Team fortress 2, guns of icarus, left 4 dead 2,... All of these were multiplayer only too, at least when and how I played them. As long as they're honest about what you're paying for and don't pull some shenanigans like promising a single player mode "soon" but never delivering, it's the consumer's own call.
