How difficult?

How difficult do you want a TD to be?

Around 50 levels? How about a TD that just stretches on for as long as you can play it? Please answer.

I don't think I ever played a TD that had infinite levels, that would be great as hell. The ammount of levels in a TD can differ depending on what kind of TD it is. For example, competetive (player vs player, team vs team) should have many levels (infinite, 40~50) so that the players can enjoy a long, drawn out game that doesn't end before one side dies.

Solo survival TDs should have many levels especially, it can be annoying to play a long game only to find that there's no winner. Infinite rounds might be the right way to go for that...

Team vs Team type TDs are about the same as solo survival, you want enough levels to make sure there's a winning side, and no draws.

TDs with one large team can have less levels. I find that maybe 30~40 levels are fine, but some people may want 50. You don't want the game to be too long, because players can get bored of the same map if it goes on for 65+ levels.

I'll message you on AIM.

Nice trick, inverting the side that the section is on in your sig, to make it look better.

I'll probably just photochop it, I'm too lazy to text edit. (Don't tell me it will take longer... sheesh... when I said lazy I meant "it would be too easy")
