‘SD Gundam G Generation: Cross Drive‘
[DS] [JAPAN] [VIDEO, TRAILER] 
The G Generation series technically began in 1996, when Bandai released a series of six games for Nintendo’s Super Famicom console’s Sufami Turbo add-on, each focusing on a particular era from the Gundam multiverse. A Generation focused on the One Year War, B Generation focused on the Gryps Conflict, and so forth up to F Generation, which covered the plot of G Gundam. Instead of continuing the obvious progression and making a G Generation game themed about Gundam Wing, Bandai held on to the title. Since “G” was often used as an abbreviation for “Gundam”, it was decided that G Generation would encompass a wider scope.
(…)The G Generation’s most distinctive feature is the fact that the machines are always depicted in a super deformed fashion. This may be to prevent problems with the different proportions used in various Gundam series, but a larger reason may be the fact that Sunrise has been known to charge a heavy licensing fee for full-sized versions of their mecha to appear in video games, a problem which also plagues the Super Robot Wars series of video games. ~Wikipedia
