i saw WAY MORE actually
like fallout 3 was all molerats, mirelurks, etc, nothing that posed any real threat but just served to be 'there'
and then new vegas was like "HEY I KNOW YOU'RE ALL COMPLACENT AND EVERYTHING AND YOU FIND NO REAL THREAT IN FIGHTING NORMAL WASTELAND WILDLIFE BUT
forget YOU TIME FOR KILLER MUTANT BEES"
RPGs need MORE enemies like that, but not necessarily to the point where every encounter has something 'interesting' about it. like, mantises had a sort of schtick (being SUPER hard to hit) but that doesn't necessarily mean that it was particularly out of the ordinary, just a slight deviation from the norm, making mantis-infested dungeons DIFFERENT and INTERESTING to fight through but not necessarily a completely new addition so you don't have to learn something entirely new (just learn to cope with the slight change in combat)
what i guess i'm getting at is that new vegas didn't really need full-on 'unique' monsters, and no rpg does really needs an enormous roster of them because it would no longer be special to come across them. smaller deviations from the stock monster formula (runs at you, attempts to remove your face) is waaaaay more then enough
im thinking the complete opposite of you guys - making it more realistic
what i'd like is a sort of pseudo-realism
like, yes, the game is super forgetin tongue-in-cheek but you are explicitly unable to carry around hundreds of pounds of equipment and thus must- realistically- plan your loadout appropriately until you find a 'groove' that you particularly like. this, of course, would mean that there would have to be a ton of 'middling' weapons- like, weapons of a variety of categories that all function fundamentally similarly (IE: shotguns, single-shot rifles and machine guns that are all effective within middle range, but leaning more toward their 'preferred' range) so as to make choosing the completely wrong weapon for the job not a death sentence as much as it is simply a disadvantage
though having said that, what would be cool was if all the 'extremes' (extremely short range, extremely long range) weapons were all super powerful within the ranges they preferred but using them outside of these ranges was not extremely INEFFECTIVE, just extremely HARD to pull off (long shot cooldowns VS hordes, etc)
