Unfortunately there's no silver bullet, but I'll share my opinion/thoughts. If the game is to move up the ladder, then it's best to understand what management thinks is important. What does your boss really value, and how do you think they see you? If you know underachievers that are getting promoted, then somebody doesn't think they're underachievers. Are they more vocal/communicative about their work? Do they take your boss(es) out for lunch or hang out on the weekends? Do they dream up new initiatives and share ideas? Good work often goes overlooked, so it's probably on you to make sure your bosses know what you're up to. You might even consider seeking an objective appraisal of your work (well, as objective as possible). Does your new platform _really_ deliver enough value to warrant a promotion? Maybe, I have no idea. If it turns out that your work really _is_ undervalued, and the politics game isn't for you, then it might be better to move on.
