I was hanging out with @hhooo and @Basoon this past weekend, as we prepped for an SC in PA, and we were watching some older video from Worlds. I stumbled across a couple alarming things in this game between @Basoon and @jesseo_o. Here I have cued the video up to the turn that has the most alarming play:
Marshall begins his turn with 6 credits, and he takes a counter of off Adonis and goes to 9.
Click 1: Draw a card
Click 2: Green Level Clearance, putting him up to 11.
Click 3 Install an Upgrade in the Adonis remote, netting him a credit off of EtFs ability, to 12. Here is the misstep. Instead of adding a credit to his pool, he removes 4 singles, and grabs a 5. He sets the 5 down in front of R&D, and then discards a card to end his turn. As Ben starts his next turn, Marshall reaches out, and puts the 5 back in the bank.
In the same game, a more minor error, on Marshalls turn that begins at 8:25 he starts the turn with 14 credits, installs Vitruvius going to 15, and then Biotic Labors. He moves a 5 credit piece off for the BL, then spends an additional single to advance, followed by Shipment from Sansan, leaving him at 9. In essence, paying 5 for the Biotic.
I know mistakes happen at all levels of play (lord knows, watch some of my games), and I do NOT point this out in any way to be a slam at Marshall (who I quite like, and is a stand up dude). This is more a cautionary tale about taking shortcuts when using counters to track credits. Both of these mistakes were due to "change" being made/not made when playing cards. Could a similar mistake be made using dice? Probably, but I bet this happens a lot more often with credit counters, and probably a lot more than most people realize.
(Also, I realize a sharp-eyed viewer commented about the 5 credit loss in the youtube comments, but still thought it worth bringing up as this was the first myself or @Basoon had seen it).
