I played the first splinter cell a few months ago. It was honestly really really fun and rewarding, but there were aspects that showed its age. Some of it was trying a bit too hard to be immersive and even on lower difficulties the enemies were brutally aware of their surroundings. There are also like two checkpoints a level and each level can take upwards of an hour depending on how slow you go. Otherwise I thought it was a really fun game and the sound design was out of this world for its time
