My friends and I play a weekly home game. It's generally range limit Texas Hold'Em meaning that it's not limit where you bet either A or B, but you can bet/raise any amount in a range from A to B. Our range is $0.50-$4.00 with $0.25 small blinds. With a buy in of $20 it works nicely because you're not going to go broke, but you'll still be able to play for a while. I usually bring sixty with me each time just in case I get a bad run of cards and lose thanks to luck. (Like this past Monday when I dropped $40 in half an hour thanks to every hand I had being dropped by a 5 or fewer outer on the river).
We also do mix it up every now and then. Each of our group of 8 people gets to do two "special" hands. "Special" is defined as anything not the typical range limit Hold'Em game play. So we'll play Omaha, 7-card stud, Pineapple (It's just like Hold'Em, only you're dealt three cards. After the flop comes down, if you're still in the hand, you MUST throw away one of your cards and then take your action. It can be tough if you flop two draws, or a moderate strength hand and a greater draw and have to decide which card to dump), or Chicago. Chicago is 7-card stud where the highest spade in the hole wins half the pot. So if you are dealt the Ace of Spades in the hole, you will try and get as many people in the pot as possible since you will get half the pot at the end. In addition, if you wind up with the best hand you will get everything. One of my buddies got a straight flush with the ace of spades in the hole and made a fortune. I've also won half a pot when sticking around with a ten of spades and at showdown seeing that my opponent had no spades in the hole. So I got half.

We don't play any games with strange wild cards or difficult rules, however, since for many of us "poker night" is also "drinking night" so if it's too complex well be unable to remember rules and someone will ---fudgesicle--- up.

What is fun, however, is making the special hand "High Limit Omaha". This is where our range limit is bumped from $4 to something like $10. This allows people to buy in during the middle of the hand and continue the betting, as well as get more money in the pot. Usually results in $80 pots or greater when we do this.
