I can't believe people are advocating being charged proper money to play a test game with threadbare rule set, random flashing inserts and according to reports quite a few mechanical bugs and software crashes. I wonder how many passers by are totally aware how unfinished the code is that they are being charged $1-$2 for. I bet a few people walked away thinking the game was a bit rubbish too.
It's not a $7k machine until the software is in a finished state and I don't agree it should be taking money yet. I'll be playing Phil's WOZ at the London Pinball Tournament later this month and as far as I know it'll be on Free Play as all these other test machines should be too.
