One of the benefits of lockdown was I cracked out the old 360 and started playing Skyrim again. Put about 100 hours into it and decided to give Oblivion a go next but I found it really hard to get into after playing Skyrim. I think most people consider it a better game but after enjoying the graphics and combat of Skyrim, Oblivion just felt too clunky and cartoony. Lots of little things like regenerating health, weapons/armor not needing repairing, the ability to sprint etc all make Skyrim much more enjoyable imo even if a lot of the quests are a bit repetitive
I've heard Morrowind is really good although doubt I'd enjoy it as much given my issues with Oblivion. Doubt anyone will pick the first two games but I will include them for completions sake
