#1: DBP is probably the easiest language that at the same time doesnt have many limiting capablilites. You could make a dig-dug game, mortal combat, or half-life, it all depends on how hard you work at it.
#2:cant really answer that, from what ive found, its not the best, but its not bad either.
#3:external plugins are available(not sure about for free)
#4:There are patches, and the community is active on the forums, just ask questions, about 95% of the time ull get answers.
EDIT: one more thing: i dont regret getting DBP one bit, its a great program, especially for beginners(like me
), also try the demo if u want to find out what its like
Video games…they can take you places unreachable, impossible, unfeasible. They put you in the book...they put you in the movie...they put you in a world, a world that before could only be imagined.
