Dakota: Seven card stud, ace-five high-low split with declare, low hole wild for high, option to buy the river up, roll your own all day long.
Here's what that means.
Rosencrantz and Guildenstern: Like Follow the Queen on steroids. Seven card stud. If a face-up Jack is dealt, the
next card dealt up becomes low (it, and all other cards of the same rank, become lower in rank than a deuce, and they cannot be used in straights). If a face-up Queen is dealt, the
next card dealt up becomes wild (and all other cards of the same rank). If a face-up King is dealt, the
next card dealt up becomes dead (and all other cards of the same rank). A card being dead takes precedence over the same card being wild, and being wild takes precedence over the same card being low. If a second or subsequent King is dealt, the card following it becomes dead and the previous dead card becomes normal again; likewise for Queens and Jacks. A low card can still make a pair, trips, boat, or quads; a dead card is treated as out of the game.
This game is a combination of Follow the Queen (cards dealt after a face-up Queen become wild) and Hamlet (Jacks are low, Queens are wild, and Kings are dead). So it's "Follow the Hamlet".
It's basically just seven-card stud, with the increased possibility that your hand's value might change dramatically with the turn of each card. The fewer cards still to come, the smaller the chance that such a dramatic turn of events will take place. Smart players will evaluate their hands accordingly.
Bastard of Science: Five-card draw (single or triple); twos are wild for making pairs, threes are wild for making trips, fours are wild for making quads, and fives are wild for making straights, flushes, and fives-of-a-kind. It makes your draws
very interesting, and much less obvious than in straight 5CD.
Locust Swarm: Five-card draw (best as single-draw); twos and threes are bugs. A bug is a limited wild card; when used to complete a straight or a flush it becomes the highest card needed to complete the straight or flush; when not used in a straight or flush it becomes an ace (but can't, for example, become a seven to turn a pair of sevens into trips). 5CD with a single joker as a bug used to be commonly played in California, where it was called Gardena Jackpots. This game has eight bugs instead of one, so players are very often going to be drawing to premium hands - straights, flushes, and aces full (or four aces, or five!).

People nowadays look down their noses at games with wild cards, but they're not that different from the circus games that are fashionable now. Five-card double-board PLO is just another way to skew the odds towards everyone having premium hands - and that's basically all that wild cards do. You're still playing poker; you still need to be good at math and good at reading other players. It's just a different flavor, that's all. It makes the math harder, makes the mistakes bigger, and lets lucky players get luckier - great for action, great for gamblers, and great for good players who can ride out the swings.
