I tried to share my (very subjective) experience with different CE communities. Hope this could be helpful for someone.
|Cheats Downloads (quantity, quality, easy to find)
|Help for table makers (tutorials, CE experts availablity)
|The Cheat Engine Forum
|Extremely useful for table makers.
|The best to get fast help about CE itself. No flairs. Not very easy to find something.
|Cheat The Game
|Extremely useful for table makers. Very little cheat downloads.
|The most convenient way to find mods. Need registration to download files.
|Community founded by TheyCallMeTim13 (one of the authors of CE wiki) and Marcus101RR. There are only allowed open source tables, trainers. Online and paywalled cheats prohibited and could be deleted.
|Cheat Engine Net
|Almost every table on this forum was copied from FRF or OCT with original author signatures removed. Don't waste your time.
|Almost every table on this site was copied from elsewhere but with credits to original authors. Easy to find stuff. Toxic community.
|FearLess Cheat Engine
|Lots of tables. Very popular resource. Very hard to find a working table (only google search is available). There are a lot of expert table makers but there are some toxic ones. If the admins don't like you then your content could be expropriated, account banned and renamed. If you need webarchive evidence DM me.
