Hard to answer this as I have only played MGS and Playtech.
If I played games by any of the other developers, I could see myself liking DOA, Creature From The Black Lagoon, Space Wars, Bruce Lee
and 300 Shields.
But I don't play the other developers (yet), so for now my Top 5 is....
1. Dark Knight (MGS)
2. Elektra (PT)
3. Immortal Romance (MGS)
4. Jurassic Park (MGS)
5. Great Blue (PT)
That was on February 24th. Before I'd ever played Barcrest, Quickspin, IGT, Play N' Go, Bally, Betsoft, WMS, NextGen and NetEnt. This is now June 15th. And I've tried at least one game by all those developers.
You think my Top 5 has changed? You're damn right it has.
In fact it has changed so much I can't even think what my Top 5 is....I'm trying new games on an almost daily basis and I'm quite
liking quite a lot of them. But for now....if you held a gun to my head
1. IR (MGS) - While MG download casinos still exist, I'll never stop playing this
2. Gorilla Go Wild (NextGen) - loved it from Day 1
3. 300 Shields (NextGen) - Stage 4, nuff said.
4. Wish Master (NetEnt) - Fuck DOA and it's constant supply of FS rounds that pay less than 1x bet, this is my go to NetEnt slot for low rolling.
5. Raging Rhino (WMS) - Hated it at first with a passion, but it's growing on me. Music in the FS is awesome.
But I could easily have included any one out of Twin Spin, CFTBL, Golden Era, Playboy, Dark Knight, Ooh Aah Dracula, Barkin' Mad, Great Blue,
Jackpot Block Party, Super Jackpot Party, Big Bang, Wild Rockets and Steam Tower on a different day. Because I've had great fun on all of those games recently. And I've still got about 30 odd games on my "games to try out" list.
I could have serious trouble compiling a Top 30, let alone a Top 5 before too long.
