In my opinion all the newer gamemodes are absolute trash and all the gamemodes that have survived the test of time (TTT, DarkRp) have suffered greatly from all the servers being re-populated by 10 year olds being salty & cancerous in every way thought possible by human society and more.
DarkRp has absolute trash addons & staff does whatever they want & abuse.
TTT has atleast 700 rules you need to follow and some servers outright having killing a T as a rule which is punishable by being slayed for the next 5 rounds.
Sandbox has become a safe haven for the furries, weebs and bronies (no offense) and is mostly filled with Ponies, Anime girls and Furry player models.
"starwarsrp" has become the second most popular gamemode and is mostly populated by salty admins, shit gameplay and retarded rules.
SCP-RP is just weird and P2P as any job except researcher, guard, and D-class is restricted and Vip/donator only of course including all SCPs.
Breach is pretty much SCP-RP
Zombie Survival hasnt changed alot its still just make a base, defend, die, repeat and is in my opinion the least cancerous of the top tier gamemodes at the moment.
Murder is still just one person chasing around 30ish, also is the same as Sandbox
Prop Hunt is still good except the servers with the unnecessary rules and shit, really easy to hack on and is slightly boring being the hunter without hacks.
Cinema is a clusterfuck of Anime girls, furries, bronies, (insert cancerous fandom here) Etc, mostly watching said MLP, anime or other cancerous shit.
This is getting slightly longer than expected so ill list a few more then finish breakfast.
Deathrun has decreased in playerbase and just adds more maps and PMs nothing much has changed
Now this shit called "HogwartsRp" is just not worth your time as most of the times its P2P and boring as all hell if you havent grinded a fuckton.
Pedobear is hide & seek with one seeker who is (you guessed it) a pedobear who is tasked with finding and chasing down the hiders who are (you probably didnt guess it) Anime girls because why not???, its okay to be honest to just play this if you're extremely bored and you can be a casual and chat with people.
Jailbreak is only fun if played with fun people as a shit 10 year old warden with a xbox quality microphone can quickly kill the mood, the entire game is decided from the competence of the warden and his guards because they will slur and mumble and kill you for no competent reason but if its a mature warden with a good mic you can actually have alot of fun with this gamemode.
Surf is just surfing in Gmod
Bunny Hop is just Bhopping in Gmod
"KingdomRp" is a laggy mess of exploits, glitches, bugs and general trash, its mostly grind XP or whatever it takes to get a job that doesnt suck major ass but it might be P2P on some servers.
Flood is an okay gamemode and can be fun if played with friends and know how to play, pretty simplistic.
Hide and Seek is well hide and seek, you go hide and someone (the seeker) is tasked with finding you and turning you into a seeker at touch so that you aswell must go find hiders.
The rest of the gamemodes have low playerbases or are just absolute trash in general.
Its a shame that the good Fretta gamemodes were lost in the void of time and theres nobody playing good gamemodes anymore.
That will wrap up this absolute shitpost and im going to reheat my breakfast because this was so unnecessary it hurts.
