I don't recall ever seeing such a suggestion from you... In fact, you're the one that suggested more than half of the games that are listed there to begin with, no? I'm not trying to be rude, I just never remember seeing that suggestion prior to Greenhillmaniac posting it...
Anyway, I will probably scan through the list of games again when I have access to a PC (I'm on the mobile site atm) and I'll remove any unnecessary entries. The goal of the "Games" section is to list the *last* versions of games for Windows Vista (including those that don't "officially" support it but still work with it - they're listed as UNS), and some entries that are listed may not meet that criteria (I haven't had access to a PC since adding them, so I haven't had time to research all of them). The earliest entries (such as COD: Black Ops 2) I did research, and found that the sequels didn't support Vista, so they were added to the list.
Others (notably GTA V) I added because their sequels (whenever they are released) will more than likely not support (and maybe won't even work at all with) Windows Vista, however it isn't confirmed by the game developers yet. For example, GTA VI (whenever it is released) will be released outside of Vista's EOL, and as such, will more than likely require at least Windows 7 as a minimum, as most modern games do nowadays.
Although, one could argue that it could be an (UNS) instance where the game works fine on Vista, despite not being "officially" supported on the OS. We'll just have to wait until the game is released, and I will update the list to reflect the information as it becomes available (lord willin' and the creeks don't rise...).
