Innovate, don't emulate
I chose 'Other'. I think it's a shame to throw out all the hard work you put into it, so abandoning it forever should only be the last resort. But releasing a bad game just floods the market with trash and taints your reputation as a developer, so I wouldn't recommend that either. What I would recommend is to think of ways you can improve your game and make it fun at least for some demographic. Maybe add a new mechanic to it, or improve the story-related scenes, perhaps add a few story twists to it. There's always something you can add to the game to make it better and it doesn't have to take you another 2 years to do it.
