Almost 10 years away from playing. Any tips on how the games have changed?

Hello all.
I used to play poker tournaments regularly. Online during the week and in the casino over the weekend.
I studied around 14 books on tourneys, tells etc... (Harringtons 3 books, Kill Everyone, Caros tells, Decide to play great poker).
I used to watch tournament poker edge (TPE) videos, used poker stove to study and posted my to the TPE forums.

I used to do Ok. I could turn a €100 investment in to 5- 10k over a year playing 2 to 8 tourneys a day with a 1% of bankroll rule.
I recently put myself €100 in winamax.fr, got lucky early on and won €850. Having 5 months off work just now, it makes sense to give poker another shot.

I've been checking out Holdem Manager, Poker Tracker etc... and I really like the options in Drivehud 2. I also find sharkscope really useful as I have no info on who i'm playing against yet.

I was just curious if anyone had general tips on how the games have changed over the last 10 years. Any free or cheap usefull software or usefull videos? I thought there would be patreon video subscriptions for poker guides, but I can't find them if they do exist.

Anyone on here sell a good HUD setup for drivehud?

I've noticed some coaching videos around, but most seems for high stakes and cost 1k+. I'm nowhere near that level yet.

Thanks all. I'm going to try to spend a bit of time here and have good look around. I'll even try to answer peoples threads, but to be honest I don't know if my outdated experience is use to anyone or not.

Cheers all.
