Prepare for a very rambly post.
This topic is directed to the members that are generally into action games.
I would like to hear your thoughts on enemy AI in video games. Would you rather deal with a larger number of less intelligent enemies, or fewer more dangerous foes? What behaviors have you observed that you found impressive? What do you find annoying about them? How could they be improved? Before I say anything, I think it would be polite to give you all the chance to share your own thoughts first. So lets hear it!
On the topic of enemy AI it depends on the complexity of the mechanics you incorporate.
If the gameplay is meticulous and the player has to think (fighting games, stealth etc.) smarter enemies naturally accommodate that niche. If divulging towards the hack'n'slash genre however with simple swipes and button combinations (Legend of Zelda is a good example) then more enemies that have undergone lobotomies will satisfy the pace of fast fun. It all comes down to pacing.
But it's not all about how smart the computer reacts to the player, but how the player can respond to the computer - if smart enemies make the game frustrating to play they won't be having much fun. You don't want to bore the player though, so too many/too stupid enemies could start becoming a chore.
In this case, other factors also come into play, for example the environment. To avoid the monotony of slicy-slice fun times
some games compensate by giving you multiple ways to dispatch the baddies. To paint a picture, you could
just hack away until they disappear or you could trigger the 50 megatons of explosives they have in the middle of their base camp. This forces the player to think in an otherwise typical encounter, elevating the experience as you feel smart for killing 10 guys (or the super hard boss man) with one well-placed anvil.
Good game design, I feel, will use a range of different intelligences based on the player and their actions. A common example of this is the adherence to the difficulty curve, where harder enemies will start appearing later along the game. Basically the same level of difficulty/skill is there, whether concentrated in one big bad or divided across many, so really it comes down to how you use them.Don't make them too dumb though because that is always boring.
But that's my opinion.
...And this thing has become an essay
TL;DR it depends on the game
