MML and Shenmue would both be met with almost complete indifference in the market. Despite TLG seemingly being the real spiritual successor to Ico, my favorite game, I willfully admit that TLG would be similarly received in terms of sales.
Agent would be a really big deal. Since the Housers were crowned, they've only headed two new IPs, Bully and Manhunt. A Grange Hill GTA and a janky stealth game. Agent was supposed to be their first real huge scope original IP, and it was already in-development in the PS2 era.
The time and financial investment, along with the talent and promise, makes for a game of huge importance, especially when compared to the three games mentioned above, or Crash.
FFVIIR would make a bigger splash as an announcement, but I'd be every surprised if it was a bigger deal in sales.
