I would like to see Second Sight get rebooted. It was one of the best PS2 era games that not many people played but it definitely had its flaws. Despite being a 3rd person game with both stealth and shooting elements, it didn't follow the now standardized control scheme for that sort of gameplay and therefore is really hard to get in to if you revisit it. I barely remember my time with the PS2 version but I remember not being a big fan of its controls, but that was when there was no set rules for how to do stealth and cover based 3rd person controls. The PC version which I got off steam (sadly no longer being sold) was even worse, being a very poorly made PC port with limited graphics options and even worse controls almost unsuitable for KB&M control.
I am not really concerned about the graphic quality however, I personally do not find PS2 era graphics "ugly", with anti-aliasing options I find them more than adequate to illustrate what is going on within the story so if Second Sight were rebooted, I feel that it wouldn't need much graphical updates. Plus the game had a weird art style, it tried to be realistic for the tech at the time but in retrospect it looks more stylized, sort of like how Bioshock Infinite's characters aren't actually proportioned correctly but still looks interesting.
If they rebooted it with cleaned up controls, maybe made a few improvements to the AI and level design, and promoted it well as being simply a remake of a classic story-focused game I feel it would be a great success. That said, I do worry a reboot would fail to preserve the intent and style of the game. The game had a fairly bizarre story that wouldn't click with everyone and any attempt to modernize the story would ruin what made it so special to me. Also while the stealth parts didn't blend well with the action parts, I feel that both were necessary because they related to the plot and state of mind for the characters; it was a dramatic shift in tone and gameplay, going from a rudimentary cover-focused shooter to a very tense and severely weaker man sneaking around was very jarring and helped boost the story. If gameplay was modernized and refined, care would have to be taken to maintain the shift in tone, the stealth sections would need more enemies to deal with because a key part of the challenge for me was managing to remain undetected while using really bad controls, and with proper controls the stealth sections would be about as hard as the first level of Splinter Cell.
Despite all of these objections, it would bring me great joy if it was rebooted correctly; I really want to play it again but I am put off by remembering how hard the game was because of its crap controls.
Edit: just realized this sounds like I want a remake, which I think would be better but I think a reboot could work as well, it would just need to be very faithful to the source material. But yeah, I guess I was really talking about a remake more than a reboot.
