For once I actually feel obligated to call Yahtzee out as being full of it.
As others have already said, it's mostly funny, but his whining about the controls and the dog selling stuff for you in town tell me two things:
[ol]
[li] Yahtzee is a console gamer that can't be trusted with anything but WASD, left click and right click on a PC; and[/li]
[li] His claim that he spent upwards of 10 hours playing the game is false... Unless he couldn't be arsed to read the tutorials and didn't even try to click and hold his mouse cursor over an enemy.[/li]
[/ol]
Firstly, controls: Action RPGS and MMOs generally have interfaces designed for keyboards and mice. This means a hotbar activated with the number keys and even using those fabled function keys (that is, F1-F12) console-exclusive gamers have heard so much about. Also, you can click and hold your mouse button to keep attacking. I don't know what the hell he was doing but he was doing it wrong.
Secondly, the pet: Purely a convenience. In *other* ARPGs you have to go back to town every few minutes, identify your equipment (in the case of Diablo 1 & 2, not so in the case of Dungeon Siege 2) and flog it. Most ARPG players will be familiar with the eventual loot strategy of "leaving everything that isn't magical" to be as space and time efficient as possible. In Torchlight you can continue picking up everything. You just shift+click on white items to have your pet pick them up directly so you don't have to sort through them in your main inventory anyway. The only valid grievance I see here is the lack of an "auto identify" or "identify all" button.
*EDIT: Another random quibble -- Torchlight isn't just a Steam game. You can buy through at least two other download services as well as directly Runic or the publisher.
