I was finally able to play Oktoberfest at Helicon Brewery in Pittsburgh. Helicon also has BKsor (pro), ACNC, MBre (LE), BM66 and other newer games. Of the 5 mentioned, I ended up playing 15 games of Okto and between 5-10 of the others, primarily because I found Okto to be so friggin unique. I love the theme, really like the art but the animation was not great at all, but I found that I didn't care because the game was so fun. I do recognize, however, that animation can be important. For example, BKsor's was so good that it made the game so much better than it would be without it (btw, I really really liked BKsor (pro) - can't wait to try the LE version). In any event, I was very impressed with the quality of Okto. It's obviously a high end, well put-together game. I loved the tents and that it's a challenging game; it made me want to keep playing. The music was perfectly acceptable and not redundant as I initially feared.
Some problems with the game that I experienced: 1. The right ramp is challenging, but not more challenging than it should be. I never reached the barrel multiball, though, in part because the ball popped out of the wireform on 2 occasions, which was very annoying since it is such a difficult shot to begin with. 2. The ball popped out of the Food wireform on several occasions, too. 3. I achieved the grand champion score (only because it's so new) but the system rebooted while I was entering my initials and I didn't get any credit. 4. There was no match after the game (probably just needs to be set by the owner). 5. At one point the flippers stopped working and I thought the game froze - it turns out that I was in some kind of skill-shot challenge but I apparently did not see or hear any prompting.
Despite these issues, I rank these 5 games: 1. Okto; 2. BKsor (pro) and ACNC - a tie and close seconds; 4. BM66; 5. MBre (LE).
