LW3 the second time.
The first time I bought it was in 2003, 14 years before I bought it a second time. I was brand-spanking new to owning a pinball machine. I didn't even know where the power toggle switch was when I bought it and thought it was broken. I sold it to get the downpayment I needed to buy the DeLorean.
After 14 years and being 20+ games in the hobby, I wanted to bring it home a second time as it was "my first", and I remembered "how hard" it was - knowing my skill level had changed quite a bit since then. I blew right through the game's wizard mode the first night I had it, and I sold it in, what was for me, a record 10 days of ownership.
