how good is gta 5 online?

I don't play GTA Online, but private FiveM servers, search on YouTube, it's awesome private moded servers

Most of GTA V is crawling with hackers and money droppers, I'd honestly get GTA V and use the FiveM mod. It's mainly zombie survival or roleplay servers but there a ton of fun and have their own anticheat measures.

Its good except for the part when a hacker or a troll arrives killing you all the time

I will be not a good idea to buy this game. Community kills it in any ways

Too many griefers, trolls, hackers and mad kids. Rockstars themselves adding only stuff for donators/moneyhackers. in-game itself you can or waste months to grind cash for something worthy or hack and probably get banned.

Troll are in all game but gta 5 have a good community for troller and hackers lol
i think gta have to clean up a lot of hacker account for really enjoying the game

Kids hackers are everywhere, don't even think about play it.

buy it and see yourself.
i play it on PS4 but i got a modded account and its no fun anymore

It is a little dated now/run down by hackers (which is funny) but my son still plays it from time to time. Try it out
