Wasteland looks pretty colorful and cartoony (characters, colors and story) for a spiritual ancestor of Fallout. Looking at the Kickstarter page, the pitch art for the Wasteland 2 (while nice looking) sort of clashes with the so clearly expressed sentiment to stay true to the original. On the other hand, I don't mind when a different style is used, as long as the designs are intact. On the other hand, Wasteland 2 has an opportunity to be graphically distinct from "brown brown black gray brown" and "brown gray brown brown black". I guess Borderlands is a bit more lighthearted stylistically, but I've never played it. Last Armageddon has one of the best settings of any post apocalyptic game I think, but now I'm derailing.
Anyways, I decided to draw some of the characters from Wastelands. A lot of the robots are just nonsense, but I decided to struggle with what I was given and not change them too much towards what I'd like to see. The game actually uses the same portraits for different encounters, so there's some room for doing variation once the base has been established.

Wiki page with refMobygames page ... Dang, I forgot to do VAX and the Scorpion tank. Maybe later.
Edit: I doodled some more while watching a nicely produced
Wasteland Let's Play. Here I've used the 4 head tall figures from Wasteland's overhead view (people have more normal proportions on the encounter portraits though), but changed the perspective from what appears to be a sort of top down cavalier projection to a typical isometric one.

Wasteland certainly has components of what we now consider a typical post-apocalyptic game, but it also have this... atmosphere of 18-19th century type story telling. At one point in the game, the player's party enters a garden with giant wondrous fruits and vegetables. Apparently someone has made canoes out of giant banana skids. I could almost see Alice, Dorothy or (Beanstalk) Jack stumbling into such a place. This made me add the giant mushrooms wrecking the asphalt. There's also a type of haphazard, carefree quality to the storytelling which makes me think of older stories rather than our modern, formalistic 3-act, moralizing ones. Vengeful baby with gun!
I drew some random figures on the map just to see what happened visually. In Wasteland, encounters rarely show up as figures on the overhead map, which is understandable since it's a lot of work to animate 400 different enemies and NPCs. Persistent figures also brings up a lot of problems like, guys getting stuck, blocking each other, shooting at walls during combat, permanent corpses, yadda yadda. Though... I wouldn't mind seeing an X-COM version using the Wasteland setting. There's the Ranger Center trying to discover technology, random hostiles, mutants, and robot bad guys with their own bases.
