I think ARTRAG exaggerates a bit there. The display delays would be long enough to cover any AI you would need. Now displaying is where the problem. Normally you could probably do 4 or 5 16x16 gfx enemies in screen 5 per interrupt. With you do something efficient with overlapping restoration copies, you can probably get one better, but that's about it. So even at lower framerate, you'd probably still want to limit to about 30 enemies on screen.

This game: http://www.handdrawngames.com/DesktopTD/Game.asp
has some sort of pathfinding that is updated each time you set a new weapon/object and each time a new monster enter the screen.
Is this the game you mean?
If yes, I confirm that IMHO z80 is not sufficient to give a reasonable frame rate
yes i have played tower def where monster where more smart than other , like able to do detours , trigger spells dpending on the type of attacks , type tower.
Probably on msx the tower def would be simpler , less rich , and hopefully still entertaining ?
manuel> Akin/Coredump framerate is about what was suggested here. It doesn't have as many enemies on screen (using slow copies) and moves more backgroud (with fast copies). A game like this would need a lot of slow copies.
I love the idea of a MSX Towerdefence game. I am a huge fan of the genre. Check www.towerdefence.net for more nice TD games. Ireally think this is possible on MSX with a few restrictions ofcourse. When there are not too much enemies on screen it should be doable. Check this TD out.
