From that I know you like metal gear. Because its basically the same.
Splinter cell: metal gear and now splinter cell: smackdown
I mean come on, the first mission coming from the water, main gate is locked go through the vents. Daylight stealth missions, silly silly. They might as well just make it a new ip.
You make it seem like you need to be restricted to night time and indoor missions for stealth.
There was nothing wrong with the first mission in Splinter Cell: Double Agent.
It is possible to be stealth in the daytime

.
People complained about the missions that took place during the day and argued that they involved no stealth, but thats just because they were playing it that way. I managed to get 100% stealth rating on most levels (including the daylight ones)
