1) Does Battle Isle 1 deserve to spend time at it or it would be better to dive right into Battle Isle 2 (it looks much better, controls are much better, and there's no annoying screen halves)?
2) Can I run Battle Isle 3 in fullscreen mode as in Battle Isle 2?
3) Are there some fan sites of this series?

Thanks in advance.

1) BI1 is a great game, I've replayed it many times, last time a few months ago. The game is quite short but there's no point in forcing yourself to play something you don't like, BI2 will keep you occupied for a long time.

I loved playing Battle Isle 1 and I mean after I bought it here. The control system and double screen is a bit annoying but you get used to it. I'm having a problem with BI 2 where the computer does not recognize that I finished the missions. That put me off the series for a long time but I started BI 3 today after buying Battle Worlds - Kronos, I fear that otherwise I'll never get to it.
