Oooh, here are some interesting ones!
No gamepad support (seriously)
How do we do that on a PC, without knowing in advance whether someone has a gamepad (and, in fact, what kind of gamepad)? 'Cause if I can do it without making the game unportable and without making it crash for people who don't have such a thing attached, I've nothing against it.
Not being able to navigate menus with arrow keys and "enter" and "ESC" keys.
Good point, and frequently neglected. I haven't implemented it yet, but it's on the list.
No fullscreen support.
Running in a term, you get that for free. Just start the term and then press f11 to go fullscreen.
Number pad only for movement.
Are you a WASD fan, or an arrows-only fan, or a vikeys fan?
No option to turn off the "press Space bar for more". Or at least make it so you can press any key to scroll the messages instead of only the space bar.
Now here's one I don't really understand. Are you saying you'd rather have messages scroll away before you read 'em than have the game stop until you acknowledge them? 'Cause my first thought when I see "allow any key to ack messages" is that a lot of players will be happily doing some key sequence, miss a message that could have saved their lives, and then wind up looking at the game over screen without even knowing how they died.
I mean, I agree that it's annoying, especially in games prone to "message spam". But I don't think "any key acks messages" is nearly as good a solution as keeping message spam down by using short messages, giving repeat counts on messages if they repeat rather than just showing them one at a time, etc.
Monochrome only ascii.
Used to be worthwhile to provide an optional monochrome mode for b/w monitors. But not any more.
Non-persistent dungeon level generation.
Agreed by me, but it's a matter of taste.
More than 20-30 dungeon levels. Especially when you need to go down then back up.
Hmmmm. I have a problem with "more levels than the game's content supports," but short or long games are fine -- it's when the levels become _repetitive_ that I'm annoyed.
Level draining enemies.
#@%*'n Rust monsters!
I'm fine with both -- as long as there are good ways to deal with them for players who think a little. Rust monsters that you can beat to death with a wooden club, or vampires that can't stand the sight of a good holy symbol or cross running water, are basically just a punishment for people who aren't being alert. It's when they're inescapable that they start being a pain in the tush.
Eggplant wizards.
Uh, what? I have no idea what you're talking about here.
