Okay, so I just finished playing the first ever game of the Unofficial TF2 Card Game, woot!
I used the solitaire mode on Lackey, so I was playing against myself. Yay, I won! Although I lost too, which is a shame.
I used a deck that had an equal amount of each class, and the other cards reflected that. I did this so I could get a good idea of how each class functioned, but it ended up with me hardly ever having the right cards in my hand for the classes I had in play. Next time, I guess I'll split all the classes between the two decks.
Despite playing against myself, I did have fun. This is a good thing. I was terrified that the game would turn out to be incredibly boring. In the end, it lasted 1hr 13min. Again, this came as a nice surprise. One of my main concerns was that this was going to end up being one of those games that lasted for 3 or 4 hours.
It looks like this is going to be a regular thing. It's a good way of spotting holes in the rules. I found over a dozen card errata, and the deck was only made from the 80 or so cards that currently exist.
I will admit, it was a little tricky playing against myself. I found myself not doing things because I knew my 'opponent' could counter it. Unfortunately, this is the way it has to be for a while as I'm still working on the rules while playing. I'm hoping that within the next fortnight or so I'll be able to start inviting people to game with me.
