How to express "same shit, different names" in Mandarin? I was recently discussing computer games with a friend and realised that I don't know how to express "same shit, different names" in Chinese. We were talking about DotA, LoL and similar games. If I come across as dismissive, I'm sorry, I only mention this particular example to provide context, my question is purely linguistic! 

I'm hoping to find a succinct way of expressing "same shit, different names", but if there isn't a fixed expression, perhaps someone could provide a decent way of expressing the same thing. It doesn't necessarily have to have the same tone, though, so expressions which are more sophisticated or less blunt would work just fine.
Two set phrases come up to my mind:


炒冷饭 (heat leftover meal/rice)
新瓶装旧酒 (the same wine in a different bottle). 旧药换新瓶 is a less common variation.


They're both applicable to your context. Their literal meaning is almost never used.

Example:


  大多数电子游戏的续作都是新瓶装旧酒。A lot of video game sequels are just rehash of the previous installation.
