Well if you didn't know it already but there are a lot of things out in the waist that want to kill you. But all you see is advlt forms of them when in previous games they threw in baby and runt forms to give the new player a hard time and preview of them. In morrowind the kawwala actually had several stages it went through in its life span to advlt form. They could have a worm that later becomes a butterfly and so on. It is a bit odd to run into all advlt creatures and yet you find eggs. I supose you could say that they grow so fast and all the same size that you don't nottice. lol

The rad scorpions we found were an oddity in that they had no venom, very strange. They did however remind me of their pre land stage. Yes, you heard me they use to be only found in the ocean long before dinos and before anything walked on land. But that’s another story.

Why there are no fish or sometime of animal in the water that tries to kill us? crocs at least should survive for Christ sake they have been around forever. And bowfin would survive so would gar they both breathe air and water, bowfin have been around for 100 million years a nuclear Armageddon wouldn't wipe them out if the chixilub meteor didn't. There are just so many things you guys missed out on. Another potential predator is the dessert snakes and spiders. You had giant ants but no snake or spider? What do you think people are more afraid of? Also it is a tad bit disappointing that the dogs and such don't actually bite you but the air around you and somehow you bleed lol Also you would think if I wore power armor dogs, mole rats and such at best should only be able to give me a headache when I’m wearing it. Of course there probably won’t be any rivers or anything in NV but I felt I needed to mention it for further games.

Anyway what do you guys think they need to add in as well?

Yeah, there should be baby, toddler and young advlt versions of creatures IMO.

It was reather weird that there were no fish in DC's water, but I don't know, is there fish in the river at hover dam?

Spiders, myeah, only reason I have against it is that it's been done to death in video games and films.
Giant spiders just don't give the same shock anymore, more like "oh great, another one..".

Snakes, I think snakes would be really hard to animate into the game and that they would clip through the landscape alot.
It would've been easier in the old games because they were in 2d form.

Whilst it is now a bit late to be wanting new or different stuff in FNV there is a http://http://www.gamesas.com/index.php?/topic/1097608-what-do-you-want-in-new-vegas/ rather than starting ones on whatever idea comes to mind.

If it is an idea for future FO games, then http://www.gamesas.com/index.php?/topic/1094022-fallout-4-speculations-suggestions/ to use.
