i've found that there are alot of games that seem stupid at first, but if you really give them a chance, they are awesome.
for the longest time, i never saw why people liked Donkey Kong so much. it was very difficult and frustrating....i set the high score on my freind's cabinet at 16,000, which is very low, and it stayed like that for a long time. but then a few weeks ago, a few of us started playing again and really started to get into it. it can still be very frustrating, but also very rewarding when you do well. the other day i set a new high score at 85,100...and let me tell you, that feels awesome when you have a good turn like that.
while i havent really played bomb jack, there seems to be a pretty big following for it, so I say give it a chance before you just dismiss it..it could be really good.
