Steam's dominance in the PC gaming market is being challenged by new platforms, including the upcoming "GameTop," a gaming marketplace being developed by ByteDance, the parent company of TikTok. GameTop is aimed at overseas markets and is part of ByteDance's strategy to enhance its gaming division under new leadership. The initiative follows a shift from aggressive expansion to a focus on operational efficiency. There is an existing app named GameTop on the Google Play Store, which is unrelated to ByteDance. ByteDance has made progress in the Chinese gaming sector and is attempting to expand internationally, though it currently does not compete with Tencent, which has a significant stake in Epic Games.
