There's some reviews out there, but ones written way back when or shortly before the game came out, and you know how that goes with PC games...so I was hoping to get a reasonably fresh perspective on it.
Being that I purchased the above mentioned Kamyran's Eye II, and also purchased Legerdemain, and plan to send off a postcard for LambdaRogue when the next version hits, I clearly have a precedent for throwing some degree of money at these things on top of the console and handheld side of the equation. I posted on the forum they have for the game that hasn't seen use in quite awhile, and there also noticed that the developer's website is down and has been for quite some time so hopefully that'll help.
As you can see the game also seems to contain a rather robust editor, which leads various cogs to turn in my head about having things get a tad more lively with it around these parts and others down the line when I and others could pick at it. I should say the existence and inclusion of such an editor does a fair job to add value to the package in addition to the game itself compared to Legerdemain and Kamyran's Eye II, which lack such a feature---perhaps more value than the game itself if elbowgrease is applied.
I can't say I see any ethical qualms for paying for Roguelikes versus the spirit of communal and individual ingenuity though. Like everything else in the videogame world, you do what you can, as you can, as the notion strikes you and what happens will happen for good or ill.
Hopefully somebody else here can weigh in else it looks like it'll be on me to take the plunge for the chance of later being able to enrich things around here, especially as if it does go OOP somebody will need to be a source for whatever form the game might be able to ultimately take.
