There are still a few of the good old NetEnts available to play, Wonky Wabbits and Wild Rockets are two that spring to mind, although they'll be on the 'end of life' chopping block soon I believe
As for Narcos, have we established what its variance actually is? It could just be that the reports here are folks running badly on it when its variance is still relatively sensible. The old WMS slots that were very much medium variance could still do some damage if you caught them wrong.
I have no real interest in playing stupid high variance monsters. You know how many spins in real play I've put through The Final Countdown since I hit that 5698x stake win? Zero. Not a single one.
I did rag the arse out of it in free play for a few hours though at £1 per play, lost a shitload of pretend money and didn't come anywhere close to getting a decent bonus round.
