I've never played an Adrift game before, so I was particularly interested in what this would be like. As I'm not running Winodws, I used the SCARE interpreter. I can't say I'm terribly impressed by the system, but it's playable, and that's what counts, I suppose.
Enough about the system. Vendetta is quite an ambitious game, set in a future that reminded me of Neal Stephenson's The Diamond Age. The writing has flaws, but the author seems to have approached the task with enthusiasm and, with a little more experience, I'm sure it'll improve. The major problems are with the design of the game, however.
Conversation is static, giving the player only the choice to "talk to" somebody or wait as the conversation unfolds. There are large portions of the game where this is the only interaction. Typing "z" or just hitting enter isn't fun. I'd be willing to give a little more leeway on this if the writing was better. Unfortunately, along with memories the PC has, conversation is often used for clumsy exposition. There are other problems. The idea that the player's girlfriend has no idea about his past or that his is asexual until a conversation during the game stretches belief to straining point.
The SF elements are also poorly done. Good SF is generally an extrapolation of current knowledge. Unfortunately, the author doesn't seem to have any current knowledge. At one point he mentions that the PC's muscles are made of "multiple amino acid chains". This is the Star Trek strategy of throwing in scientific terms without any reference to reality.
I'm being harsh. The game does show some signs of sparkle and imagination, and in parts it is very good. Unlike a few entrants to this comp, I'd encourage the author to keep at it.
Unfortunately, the funniest line from the game comes from the climax. I literally burst out laughing at this: "Execute! Execute!" The griffon crows in a staccato parrot-like voice."
