Sega has undergone a restructuring and everything that they have been releasing since has been of the highest quality. You might not like the games, but they are well polished, they are translated in the main European languages etc...
There has been a huge focus on quality, and it is very easy to see this (when you actually play the games). I am not going to make a list, this is stupid. But it would be great to stop saying that they have been making shitty games as this is not true anymore for quite some time now.
There was a dark period between 2004 to 2008? Where they made 3/4 bad Sonic Games in a row (I count Heroes as I hate that game), and Project Altered Beast, Shinobi on PS2, NiGHTs Journey to Dreams and I think Golden Axe: Beast Rider were not that great (Shinobi PS2 was more difficult than anything), but in terms of what happened with them under Sammy at that time, I could understand why they were still finding their feet after losing some staff.
Yuji Naka should have stuck around if not for the fact that he is a good programmer (just not a great PR Mouthpiece), but at least Nagoshi got to nurture Yakuza when it was still a young project, and Queen Kodama has stuck with SEGA since the beginning.
I would actually say that SEGA's efforts post 2008 have been really good if we ignore Sonic games (although I love Colours).
Renegade Ops was a pretty great game too even though they published that one, Valkyria Chronicles was a great game but released at the wrong price point (as evidenced by the Word of Mouth it got later), Phantasy Star Universe was good but SEGA of America made everything come much later and lost goodwill on that, and I would say that despite the low sales of Platinum Games, it kind of established P* Games from the experiences since we now see them making great games for other companies (for better or worse, SEGA letting them go out of contract was a great decision as we wouldn't have had NieR Automata or Astral Chain!) We also got the All Stars Series which is amazing and I am at a loss on why they didn't continue this.
Despite things with the Shining Series, I do like the new Shining Resonance being like the Tales of Series as well. Would love a new Shining Fore as well however!
I tend to ignore people when they say that SEGA have done shit or crap games over the years. Every company has blips! (I would say that Capcom/Konami have had a much harder fall from grace during the PS3/360 era with Capcom trying to cater to America/Europe and ruining their new IPs a few games later such as Dead Rising and Lost Planet, and Konami seeming to have lost the plot on Castlevania games and delaying MGSV).
I will confidently say that I have supported SEGA the most post-Dreamcast era during those "bad" times they had, and still enjoyed their games even when they were mocked, and now we get to see them flourish with ATLUS under their belt and suddenly you get these gamers who shat on SEGA all these years now coming out of the woodwork to say "SEGA have vastly improved". It's the direction in SEGA that has improved as the Developers never "lost" their talent, it's just Sonic Team dragged the quality down with the changes to Directors (and leaving Ilzuka in charge of all things modern Sonic), and the memetastic Sonic Twitter also not helping matters.
I still think there could be improvements on the Western side as I think that despite the Mega Drive Mini being an amazing piece of kit and has some decent games on it vs the collections of the past, giving us the same Alex Kidd/Altered Beast/Virtua Fighter 2 combo is annoying as those games are no longer a selling point in Europe or America since they are everywhere, and Konami's Rocket Knight Adventures was a no brainer for the Konami Trio for the Mega Drive. However, I do think the Western side are heading in a better direcion than a few years ago.
