Hey,

Majority of the games listed already dead or discontinued, as for the improvements, partially of them got updated and some didn't.
There are some games not worth the time and effort to support or improve as it's not beneficial at all.
Trust me tho, I am all up for improvement and rebuilding/redoing old stuff, but SystemFiles is strongly against it as soon as it becomes too much of a "time consuming" project, which to be honest with he, he barely have that free time as he used to.
As for new games, there is really nothing interesting to cover, with new AC's, focus will have to be shif and it's not something he want to bother with. It's going to be dealing only with AC updates or maintaining current popular games. He won't be able to maintain both.
We had a lot of planned games and even some had almost fully working cheats such as Warframe/Destiny 2, but again with how limited his time is and the amount of updates these games received, he couldn't continue..

I know for a fact he is very interested in making new cheats and improving, but time.. This is the biggest enemy right now. You may think SystemFiles is a machine that only sits on his ass and coding 24/7 but I promise you this is waaaay far from it.
P.S.. There will be Christmas sale, so you might want to wait for it if you want to get Premium. But, as for the main question, will he add SystemBot to SystemRadar cheats? Very unlikely, at least with the current cheat list.
