Both.

If this is sort of an action game, where hit points, resistances and the like don't matter,  then just use sounds and perhaps have a "learn game sounds" area if there are any which you think might be difficult. Best for full sound immersion. In an RPG setting, where a hit isn't necessarily a kill and might in fact be a bad thing (counter-attack, reflect/deflect, etc.), then you could go sound with text, or even pure text, depending on the ammount of immersion you want.

I'd deffinately agree on sounds pluss text for a game like jungle adventure. Sound has a lot of immertion and atmosphere potential which shouldn't be overlooked, but obviously for a roguelike with complex navigation and mechanics you need text to express many of the concepts, ----- afterall, expressing lines of site in sound could be problematic.

Actually I must admit, reading the tactical maps thread, I thought you were just going for pure text, which as jayde said, for this sort this sort of game would be fine, but if your going for sound as well, ---- great!

Depending upon how far you want to use sound, some possibilities do exist to speed up game play. For example, if your character attempts to walk through a wall having an oof sound, using a click or confirm sound for equipping items once you've selected them in your inventory, and of course a good old fashion dramatic death sound needs no clarrification, ;D.

for many things though, such as the amount of hp you heal, where you move to on a complex interface, and how much damage you do enemies in situations when they aren't instant kill fodder, I'd stil go for sound pluss text.
